The Mukaiyama aldol reaction of silyl ketene acetals with aldehydes has been effected by using commercially available 4 angstrom molecular sieves (4 angstrom MS) as a promoter. Various silyl ketene acetals and silyl enol ethers have been shown to be effective nucleophiles for this reaction. For the first time, it has been found that 4 angstrom MS can promote the Mukaiyama Michael addition reactions of silyl ketene acetals to alpha,beta-enones.
