THE CATALYTIC ASYMMETRIC ALDOL REACTION OF ALDEHYDES WITH UNSUBSTITUTED AND MONOSUBSTITUTED SILYL KETENE ACETALS - FORMATION OF ANTI-BETA-HYDROXY-ALPHA-METHYL ESTERS
The title reaction with unsubstituted and monosubstituted silyl ketene acetals proceeds with high enantioselectivity, and in the latter case good diastereoselectivity favoring the anti-beta-hydroxy-alpha-methyl esters in all reported cases.
