Input (English): One modification of this reaction uses an active hydrogen compound with two strong electron-withdrawing groups in order to synthesize a conjugated enone and is named for Knoevanagel, and Evans used a chiral oxazolidinone auxiliary to make it stereoselective. Many of its derivatives follow the Zimmerman-Traxler mechanism, with the exception of the version using a silyl enol ether known as the Mukiyama variation. It also follows a Michael addition in the two-step Robinson annulation, and its base catalyzed variant creates an enolate nucleophile which then attacks a carbonyl. FTP, name this condensation reaction whose namesake product is a beta-hydroxy ketone.
Output (English): Science
