CONCEPT QUESTIONS Mechanism. While the reaction carried out in lab used potassium hydroxide as the catalyst, many other catalysts have been developed to increase regioselectivity and stereoselectivity in aldol condensations. One small molecule catalyst commonly used is proline, a naturally occurring amino acid. a The mechanism involves the initial formation of an enamine; predict the structure of this enamine intermediate (intermediate Al and draw the mechanism for the conversion of intermediate A to intermediate B. Helpful Hint: The formation of...

Organic Chemistry 2
Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...

For the following reactions fill in the box with the missing major organic product. Make sure to include stereochemistry when appropriate. If a reaction affords a mixture of enantiomers draw only one enantiomer. In the space below the reaction draw a detailed arrow pushing mechanism for that reaction.
