摘要
Amphiphilic calix[6]arene derivatives 1a-b were found to be efficient surfactants for Sc(OTf)(3)-catalyzed Mukaiyama aldol reaction of silyl enol ethers with aldehydes in water. The results indicated that a hydrophobic microenvironment was formed in the reaction system, which is favorable to stabilize some labile silyl enol ethers and thus promotes the reactions.
