Abstract

An account of our most recent developments on the synthesis of various fused heterocycles via alkyne cyclization is presented. The synthetic strategy involves N- or O-propargylation of heteroaromatic or aromatic compounds followed by intramolecular gold-catalyzed or NaH-promoted intramolecular cyclization reactions. This synthetic strategy represents a reasonable methodology for the construction of hitherto unknown skeletons. (C) 2020 Elsevier Ltd. All rights reserved.
