摘要：

A mechanistic study of the Mukaiyama aldol addition reaction employing benzaldehyde and hydrocinnamaldehyde along with a selection of Lewis acids including BF3.OEt(2), LiClO4, Yb(OTf)(3), Sn(OTf)(2), and Zn(OTf)(2) is presented. The results of experiments conducted with doubly-labeled silyl ketene acetals implicate a Lewis acidic silicon species and not the metals as the catalyst in the Mukaiyama aldol addition reaction.
