Copper-catalyzed N-arylation and aerobic oxidative C–H/C–H coupling: one-pot synthesis of indoloimidazoquinoline derivatives

Author affiliations

Abstract

A novel and efficient copper-catalyzed one-pot synthesis of indoloimidazoquinoline derivatives has been developed. The protocol uses the readily available substituted 2-(2-bromophenyl)-1H-indoles, imidazole and benzoimidazoles as the starting materials, inexpensive CuBr as the catalyst, air as the terminal oxidant, and the procedure underwent a sequential copper-catalyzed intermolecular N-arylation and an aerobic oxidative intramolecular C–H/C–H coupling.
