Abstract

A catalytic amount of lithium perchlorate suspended in dichloromethane provides a mild and effective medium for Mukaiyama aldol reactions of aldehydes with silyl ketene acetal (1). 2-Cyclohexenone undergoes clean 1,4-addition under similar conditions. Catalyst activity is much higher in dichloromethane than in diethyl ether.
