Abstract

Stereochemical studies have indicated that functionalized Tr ⁺ SbCl ₆ ^- may serve as efficient aldol reaction catalysts by judicious choice of a silyl component. The aldol addition between TMS ketene acetal derived from γ-butyrolactone and benzaldehyde provided the silyl aldolates with high syn diastereoselectivities.
