摘要

A method to prepare N-acyl enamides is reported that is complementary to the existing protocols. Heck reaction of a variety of aryl trifluoromethanesulfonates with commercially available N-vinylacetamide occurred in a highly regioselective fashion to provide these valuable synthetic intermediates. This method permits the formation of N-acyl enamides containing functionality that would not be tolerated by the existing methods. Asymmetric ...
