Abstract

A vinylogous, silylative, and direct variant of the venerable Mukaiyama aldol reaction has been developed. Exploiting N-Boc-pyrrol-2(5H)-one as the conjugate donor, several aldehyde and ketone acceptors were scrutinized under the guidance of suitable dual Lewis acid-Lewis base activators to provide a varied repertoire of functionality-rich alpha,beta-unsaturated-gamma-amino-delta-silyloxy carbonyl structures, in useful yields and often with an exquisite level of diastereoselection.
