For 10 points, name this condensation reaction whose product has characteristics of both aldehydes and alcohols.
Chalcones are produced via this reaction between benzaldehyde and derivatives of acetophenone. One mode for controlling selectivity in this reaction is the avoidance of syn-pentane forms in its transition state according to a model proposed by Zimmerman and Traxler. That model is not followed by a reaction using silyl enol ethers to add to aldehydes in this type of reaction named for Mukaiyama. The product of this reaction readily dehydrates to form an alpha-beta unsaturated carbonyl, an enone or enal. This reaction follows a Michael addition in the Robinson annulation. Its first step under basic conditions is the abstraction of the alpha hydrogen from an aldehyde to form an enolate. For 10 points, name this condensation reaction whose product has characteristics of both aldehydes and alcohols.
