Abstract

Microwave‐assisted and organobase‐promoted eco‐friendly one‐pot protocol has been developed to construct an interesting class of pyridyl‐substituted phenols/α‐naphthols containing a carboxylate or aroyl group at C2 position on the pyridine ring. A series of N‐sulfonyl ketimines and different kinds of bielectrophiles, such as MBH acetates of nitroalkenes/α‐arylacetylenyl‐β‐arylnitroolefins, were involved in this cyclization process, which delivers good to high yields of aforementioned heterocycles and excels with several compatible functionalities.
