Abstract

Abstract An efficient method for the synthesis of 2, 4, 6-triarylpyridines via microwave- promoted and BF 3 OEt 2-catalysed one-pot reaction of ω-pyrrolidinoacetophenone with chalcone is reported. This method illustrates urea as an environmentally benign source of ammonia for the synthesis of 2, 4, 6-triarylpyridines.
