Direct N-Acylation of Lactams, Oxazolidinones, and Imidazolidinones with Aldehydes by Shvo’s Catalyst
摘要:
Direct N-acylation of lactams, oxazolidinones, and imidazolidinones was achieved with aldehydes by Shvo's catalyst without using any other stoichiometric reagent. The N-acylations with alpha,beta-unsaturated aldehydes were achieved with excellent yields.

[reaction: see text] A fast, flexible, and efficient approach for the stereocontrolledsynthesis of enamides has been developed starting from lactams and amides through the use of imides. This new approach provides access to enamide systems not easily or currently accessible through other approaches.
