Consider the following crossed aldol condensation. Which statement explains why a single cross condensation product is formed? 2,2-dimethylcyclohexanone "CH₃ H₂C, CH, H NaOCH.CH H3C thanol benzaldehyde 2,2-Dimethylcyclohexanone has only one alpha carbon which can form an enolate. Benzaldehyde has no hydrogens attached to the alpha carbon which eliminates the self-condenstation reaction. 2,2-Dimethylcyclohexanone is sterically hindered which limits the self-condenstation reaction. All of the above

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.
