SYNTHESIS OF 1,8-NAPHTHYRIDINES: A RECENT UPDATE

Abstract

This microreview focuses on the recent achievements (2015–2019) toward the synthesis of 1,8-naphthyridines, which include multicomponent reactions, Friedländer approach using green strategy, hydroamination of terminal alkynes followed by Friedländer cyclization, metal-catalyzed synthesis, and ring expansion reaction of 3-substituted 1H-pyrrolo[2,3-b]pyridin-2(3H)-one.
