Abstract

magnified image

A series of 2‐p‐tolylthiopyridine derivatives was directly synthesized via three‐component reactions of chalcones, malononitrile, and 4‐methylbenzenethiol catalyzed by Et~3~N in DMF under microwave irradiation. It is an efficient and promising synthetic strategy to construct 2‐thiopyridine skeleton with the advantage of short time, excellent yield, and convenient operation. J. Heterocyclic Chem., (2009).
