Synthesis of Indolizine-Containing Diaryl- and Triarylmethanes through a Cu-Catalyzed Domino Cyclization of 2-(2-Enynyl)pyridines

Abstract

A Cu‐catalyzed protocol for the synthesis of indolizine‐containing diaryl‐ and triarylmethane derivatives through a 5‐endo‐dig cyclization of 2‐(2‐enynyl)pyridines, followed by a remote addition of nucleophiles, such as hydride and 2‐naphthols, is described.
