  • We've learned some enolate chemistry using ketones and aldehydes as substrates, so let's learn the Claisen Condensation, which uses an ester substrate, as well as the intramolecular version, called the Dieckmann Condensation.

    My professor NEVER said the OR's had to match when we were doing this in class. That kind of upsets me about that. This is actually very useful information. Thanks

    My Professor didn't do a bad job at explaining this. In fact my organic chem 1 and 2 professor (same guy) was actually one of the best professors I've had. Professor Dave just has a way of explaining things though that just helps so much. Awesome vid!

    What if you use a different base to remove an alpha proton? Can you use NaOH or would the ester be prone to base-catalyzed hydrolysis? What about sodium hydride or amide (NaNH2)? I'm assuming NaNH2 would create an amide but not sure about NaH.

    4:40 Wouldnt part of the intermediate react into an alcohol, rather than the desired product? If the charge is on the oxygen, it would also be protonated, wouldnt it? If this is true, how can you isolate the final product and if this is false, why doesnt this happen?
