Disease relevance of Acyloin

• [reaction: see text] Benzaldehyde lyase from the Pseudomonas fluorescens catalyzes the reaction of aromatic aldehydes with methoxy and dimethoxy acetaldehyde and furnishes (R)-2-hydroxy-3-methoxy-1-arylpropan-1-one and (R)-2-hydroxy-3,3-dimethoxy-1-arylpropan-1-one in high yields and enantiomeric excess via acyloin linkage [1].

High impact information on Acyloin

• The preparation of the corresponding C.1-C.12 segment of amphidinolide Y relies on asymmetric hydrogenation of an alpha-ketoester, a diastereoselective boron aldol reaction, and a chelate-controlled addition of MeMgBr in combination with suitable oxidation state management for the elaboration of the tertiary acyloin motif [2].
• Carbene-catalyzed acyloin condensation of beta-aldehyde 10 followed by acetylation provided a separable mixture of diastereomeric (2S,5RS,7S)-diamino-4-oxo-5-acetoxysuberates (13) [3].
• Minor side reactions involving the AR, the substrate acyloin, and the vinyl ester acyl donor were also observed [4].
