Copper-catalyzed tandem cis-carbometallation/cyclization of imine-ynamides with arylboronic acids

Chem Commun (Camb). 2020 Apr 30;56(35):4832-4835. doi: 10.1039/d0cc01424a.

Abstract

An efficient copper-catalyzed tandem regioselective cis-carbometallation/cyclization of imine-ynamides with arylboronic acids has been developed. This method leads to a facile and practical synthesis of valuable 2,3-disubstituted indolines in moderate to excellent yields and features a broad substrate scope and wide functional group tolerance. Other significant features of this protocol include the use of readily available starting materials, high flexibility, simple procedure and mild reaction conditions.
