Well, considering that the euphoria is principally provided by the compounds action of inhibiting the release of Serotonin, do you really think he would be able to produce that much serotonin that many times a day? Someone here is not telling the truth, and I bet it’s Freud. He shouldn’t even have been able to use it in a daily basis for long periods of time and produce any results. The damage to his body’s natural functions would be untold.
Absolute mad lad. If I recall right he accidentally invented the epidural block by deciding on a whim to inject cocaine into his spine. I can only imagine what his notes were like on that one... "Experiment has failed to imbue 'spinal confidence'. Actually now I've come down a bit from this morning's more usual dosage I'm not even sure 'Spinal Confidence' makes sense as a concept. Anyway. Sure do hope this paralysis is temporary!"
It was also our entry point to topical anaesthetics, and from there, nerve blocks. For a long time, ether was the only anaesthetic, but came with an extreme risk of sudden death. Many, many people died on operating tables from ether, including women in childbirth. Cocaine led us to epidurals.
The total synthesis of morphine is really interesting too, it’s something like 13-15 steps. Completely non viable for industry, but there are some cool steps.
@@stefanschleps8758 it’s making morphine from scratch that’s that many steps. It’s so complex and low yielding that we just let the poppy plants do it because it’s just a simple a/b extraction at that point. Though there are genetically modified yeasts that can produce opioids now but I haven’t heard of them being adopted for production purposes yet. Morphine to heroin is one step, that’s true. It’s just an acetylation.
@@Srax499the lie is that it doesn’t elevate the mind, it alters it by inducing a chemical reaction which subjects the user to euphoria. Which works but is ultimately the illusion of elevation, True elevation would genuinely enhance function. And from what we know of cocaine users, they aren’t more cognitively adept then those of a sober mind.
The best part is that if the acetone dicarboxylic acid is a semi-ester, the second decarboxylation doesn’t occur and you get the perfectly substitute product in one step.
I had to read this a few times to comprehend 😂 good argument for a video on chair structures! Semi-ester though... I'ma be hitting the literature to see what that is.
@@SharpAssKnittingNeedles By semi-ester I just mean one one the two carboxyl groups in acetonedicarboxylic acid is esterified and the other is free. So, the free one undergoes decarboxylation but the esterified one remains as-is. This helps since you don’t need to do a future re-functionalisation.
@@totalsynthesisAnd such beautiful chemistry! My ochem prof promised us that we'd make him proud by quickly and efficiently making meth cuz Walter White was the worst most inefficient chemist ever 😂
This information isn't going anywhere, it would be way more expensive and dangerous to try this method plus it's so ridiculously complex that basement chemists wont even bother. I'm fascinated that people even figured this out, life sure is amazing.
Really love this video. Funnily enough, my masters project was to figure out how to synthesise the core skeleton of a tropane in a structurally related tropane to cocaine through a [3+2] nitrone-alkene cycloaddition - it didn't work and I made pyrolles but man, that original synthesis via the Robinson's route is one I have in my thesis introduction. Love the chemistry videos from you, keep it up.
That's so cool, you made a pseudo cocaine Is there a way to make cocaine longer acting, and so suitable as a replacement drug? Similar to buprenorphine
@@90klh I didn't make it, the methodology doesn't work - to form a tropane from the [3+2] approach, the major competing reaction is dehydration-aromatisation to pyrolle
@@totalsynthesis It's not going to last. A while ago someone published a video on machining a certain device capable of accelerating projectiles in a form factor suitable to hold it in your hand. Despite the fact that this was completely legal in his jurisdiction, he did not give exact instructions or published CAD files, and the fact that you need orders of magnitude more expensive machines, tooling and material vs what it costs to just buy that device, the video was gone in a matter of hours.

Actually, if I think about it: 1.) acetone dicarboxylic acid can be made from citric acid by oxidative decarboxylation in sulfuric acid below 10C 2.) methyl amine can be made from acetamide and bleach in a hoffman degradation (and acetamide is made simply from ammonium acetate) 3.) succinic dialdehyde is the tricky part… it could be made from THF by breaking the ether bond with sulfuric and water followed by CrO3/Pyridine oxidation To make the acetone dicarboxylic acid semi-ester, it should be enough to turn it into the salt and react it with a methylating agent while keeping the dicarboxylic salt in great excess and the solutions sufficiently diluted. Then it’s just a matter of separating the semi-ester. Another way would be to dissolve the free acid it in a dry cold etheric solution and add a diluted etheric solution of sulfur trioxide which should steal water and turn it into the anhydride. Then, when nearly all is reacted, in the dry etheric solution add some methanol and warm it up. This should break the anhydride bond and form an ester and a carboxyl acid group. Separating the mono-ester shouldn’t be too hard in either case, the calcium salt of the di-carboxylic acid is water insoluble while the semi-ester calcium salt is more soluble. Then react them all together, make the substituted tropione, reduce the ketone with sodium borohydride then add sodium benzoate and acid and do a final esterification.
That was a wonderful and enjoyable tour through history not only of that particular compound but cehcmical history, some social history and a really detailed and engaging presentation of the chemistry. Some of that is well beyond me but certainly worth watcching. Thanks
Good job and you my friend are a fantastic chemist! Especially if you've completed this synthesis as its quite complex. Not as complex as that of LSD but still quite complex hence the natural cocaine process is still in use today. Agreed cocaine use is on the rise but the current 50-year-old obviously failed "drug war" is to blame. More police, more courts, more prisons and yet 1,000,000 dead in American and counting.

I can already imagine those biochemists discussing on what to do: "alright lads we know the biosynthesis pathway of cocaine now we have to put it into another plant any suggestion?" "Tobacco plant!" "Brilliant idea! Nicotine and cocaine in the same cigarette! You got yourself a promotion" "And make sure to fertilize it real good so those cigarettes are gonna be real special"
@@totalsynthesis You could also cover many examples of these kinds of studies explored by many different chemists. I've always been curious about how they elucidated chemical structures in that time period before modern analytical methods. Thanks!
Its fascinating that cocaine binds to the kappa opioid receptors, and honestly i think thats why it works better for (tooth) pain, in my very VERY limited experience, than lidocaine or any of it's analogs. It's like it keeps kiling pain even after the local anesthetic effects wear off. And this eas a small dose, not even enough to cause any kind of psychoactive effects..... Hrm :/ I wonder what part of the cocaine molecule interacts with kappa opioid receptors, and could we keep that, while removing the dopaminergic reuptake inhibition, like how lidocaine is a structural analoge
Kappa opioid agonists are interesting, though its effects on the central nervous system are uncomfortable (dysphoria, hallucinations, etc). Limiting the CNS effects could make them a potential painkiller though. ....And anti-itch. There's a peripheral kappa-opioid agonist used in Japan for itching due to chronic kidney disease.
@@sultamicillin indeed, their effects are less than fun, but that's kinda a good thing- talwin works quite well for pain, but causes absolutely no buzz, just a vague deadened feeling and a deep apathy But that's way better than a rush of euphoria so profound you just cry (what I did my first time taking Vicodin). I think we should use our kappa agonists more in medicine.
This is a layman’s guess but when looking at the structures of opioids they all tend to have tertiary amines, and often ketones which cocaine has both. That doesn’t explain salvinorin A though
Even if you know how to synthesize a molecule, how do you know which molecule to make? There's a billion combinations to choose from. How do scientists decide what to make?
Whatever is interesting enough from a chemistry perspective (like this molecule looks very complex, so just making it might be challenge enough - note: this school of thought is dying out) or a broader scientific perspective (for example trying to make slightly different but more potent versions of medicines). However very pragmatically, much of the research is based on what research groups believe will be publishable in journals.
@@totalsynthesis Thanks for the answer. I'm obviously a total noob, but I find it fascinating to go back in time and wonder what prompted scientists 100 years ago to choose a particular structure, not even knowing what it could be used for, and even tasting it without knowing whether it would kill them. They couldn't be bothered with rats or mice, they just tried it themselves. True heroes (or fools, depending on your point of view).
I'm not a chemist, so fogive me for not knowing, but it seems to me that double bonds (especially in carbon) seem to be less flexible. Is that an accurate observation?
Exactly as the gentleman pointed out. They can still wiggle around a bit but there is no rotation. This means the arrangement of the double bond is "locked" (whereas single bonds can turn around like crazy)
I think the tobacco yield is like 0.2 grams per pound of tobacco at a 100% yield. That looks strictly academic, but useful for building Organic synthesis machines that can do organic reactions, you cant unlock with a chemistry set.
It seems it would be a simple process for chemists to begin by extracting specific alkaloids from Datura Stramonium (atropine, hyoscyamine, scopolamine) as they are structurally similar and it doesn't seem like it would be that complex of a reaction series to convert to the target molecule.
Educational interest in chemistry that is all, nothing sinister at all. What happened in 2015 2:08 Did they start cutting it more, that curve is looking almost exponential?!
Dude, your videos are amazing! Please, include the degradative studies, those are very important to understanding synthesis as they are the reverse process. IF its a matter of screen time that you don't have, take less time with historical background and more with degradative and other REAL interesting chemistry content. Cheers!
Thanks for the comment! Yeah I didnt want to completely focus on chemistry as I wanted to have some topics be relevant for non chemists as well. Might include it in a future one!
The rise in cocaine overdose deaths is because of the fact that most of the cocaine is now adulterated with fentanyl, it’s not that common for people to OD on solely cocaine it’s almost always when it’s mixed with other things
Definitely challenging to say for sure - I found it more funny than true, although I also think drug mentions in music or media are indeed a relevant factor for newly emerging drugs or concoctions
Could they make a super opium plant, one that makes hydromorphone instead of just morphine? I mean they already made cocaine containing tobacco, imagine trying to quit smoking THOSE cigarettes. 0_o normal tobacco is bad enough
The need for 'backside' attack in direct SN2 substitutions comes from molecular orbital considerations. Put simply, kicking something out requires an approach right opposite to the bond between carbon and the leaving group
@@totalsynthesis It's been a while since I've studied mechanisms but this started a good review. The bromine pulls electron density toward itself and leaves a void on the carbon it's bonded to from what I understand and also leads to an inversion of stereochemistry at that site. Thanks for the reply.
It would probably be cleaner at least ! I’m sat here in hospital waiting room right now, been waiting over 8 hours to get sorted, my right leg is inflamed and swelling in pain from blood clots from shooting coke, and speedballs with heroin and coke mixed, I’m in agony.

what technique was used to determine the structure of cocaine? I think NMR didn't exist back then
Combination of various methods, but notably Hofmann degradation if you want to look that up
But for sure NMR and most other analytical methods did not exist
Why does the chemical structure on the thumbnail looks like its about to score a goal after doing bicycle kick?
What of im just a cocaine aficionado? Will i get anything out if this video?
Yeah...........your dealers charging you too much! 😅
@@stefanschleps8758🤣 until I learn how to do it myself from this video.
@@sobertillnoonyou should start a UA-cam channel about your advancement in cocaïne synthesis. Years and years and decades of content assured!!
I thought to myself " i dont need to watch it " *my monkey brain* "ooo ooo useless info ooo oo "
They should use the "Ask Ned Flanders how it made him feel" technique for all drug brand names.
How does your nose feel, Ned? "Numberino!"
Lmao
Freud basically secondhand created the first speedball
2:22 - So, OT Genasis is responsible for more use. Catchy song, but I have doubts.
Educational interest in chemistry that is all, nothing sinister at all.
What happened in 2015 2:08
Did they start cutting it more, that curve is looking almost exponential?!
I due to lack of education cannot understand 95% of the chemistry language but still very interesting lol 🤷♂️
Subscribed! Love your content. We about to make some moneyyyy!
The DEA hates these 25 (not so) simple steps to get rich!
Find out how, today on Total Synthesis.
Dude, your videos are amazing! Please, include the degradative studies, those are very important to understanding synthesis as they are the reverse process. IF its a matter of screen time that you don't have, take less time with historical background and more with degradative and other REAL interesting chemistry content. Cheers!
Thanks for the comment! Yeah I didnt want to completely focus on chemistry as I wanted to have some topics be relevant for non chemists as well. Might include it in a future one!
Google algorithm at its best. I didn't search for this.. This searched for me.
Yeah its fucken got ya
Excellent work! a question. What program do you use to draw the molecules in 3D?
Digital Footprint is crazy
😂
Subliminal programming cocaine use increases addiction and relapse? Interesting. Science needs to go further with new data
The rise in cocaine overdose deaths is because of the fact that most of the cocaine is now adulterated with fentanyl, it’s not that common for people to OD on solely cocaine it’s almost always when it’s mixed with other things
I'm very skeptical of a cause effect relationship between cocaine in song lyrics and cocaine use.
Definitely challenging to say for sure - I found it more funny than true, although I also think drug mentions in music or media are indeed a relevant factor for newly emerging drugs or concoctions
The direct effect would be small, if anything
Ngl, it reminded me of the graph correlating Internet Explorer usage with murder rate (quick Google Image search should turn it up).
I would have assumed it goes the other way.
I’d imagine it’s the exact opposite. Hip hop is reflective of material conditions, not vice versa
I'm literally on coke tn and wanted to watch an interesting vid about it and this popped up on mu UA-cam
I hope you watched the part around dangers and toxicity!
@@totalsynthesislol!
Learning about this is pretty interesting
Another great video!
Welcome on the Watchlist Guys!
Welcome breh
Finally, i could start my own business
Of sharing educational science information, got it
Standing ovation for this amazing lecture ❤
Thank you!
does synthesis mean making synthetic version of or just mean doing chemistry to make something?
Both things are kinda the same?
I’m definitely now on a list
Could they make a super opium plant, one that makes hydromorphone instead of just morphine? I mean they already made cocaine containing tobacco, imagine trying to quit smoking THOSE cigarettes. 0_o normal tobacco is bad enough
Tobacco is used quite often in bioengineering. It's because it grows very fast and has large leaves.
@@pseudomemes5267it’s also a matter of having exploitably similar biosynthetic pathways
25 steps sounds way too many for a tropane alkaloid, but I guess hindsight is 20/20
A truly (education) experience indeed!
Cycloheptatriene is not aromatic, however, the tropylium cation is 10:55
Yes
At 12:28, why does the amine selectively attack the anti bromide and not the syn bromide?
The need for 'backside' attack in direct SN2 substitutions comes from molecular orbital considerations. Put simply, kicking something out requires an approach right opposite to the bond between carbon and the leaving group
@@totalsynthesis It's been a while since I've studied mechanisms but this started a good review. The bromine pulls electron density toward itself and leaves a void on the carbon it's bonded to from what I understand and also leads to an inversion of stereochemistry at that site. Thanks for the reply.
Yes, also its due to the geometry of the "antibonding" carbon-bromide sigma star orbital... If that tells you something
Great video, never disappoints.
Thank you!
Great work. 👍
UA-cam showed this on my for you page for 4 days in a row i dont watch any drug related videos. I have never seen cocain in real life 😂😂
Thanks for clicking nevertheless! My goal is really just clickbaiting people into learning chemistry and science
Richard Willstätter! Albert Hofmanns nemesis!
Hey! UA-cam recomended this, so no watchlists, huh!?
It would probably be cleaner at least !
I’m sat here in hospital waiting room right now, been waiting over 8 hours to get sorted, my right leg is inflamed and swelling in pain from blood clots from shooting coke, and speedballs with heroin and coke mixed, I’m in agony.
Don’t get me wrong I know the majority of coke users sniff them powder or smoke it as crack etc, but shooting it up has caught me out.
Hi NSA agent 👋🏼
Can you the total synthesis of (-)- Hunterine A
Pretty cool one, good suggestion
Where have you been all my life? ❤
Great video!
Thanks!
-sees title- nah, theres no way.... (clicks on video knowing im ganna be ona whatch list ((if im not alreadyb😂😂)) )
