Abstract

A versatile and transition metal-free approach for the synthesis of new 7-methylene-6,7-dihyrobenzo[f]benzo[4,5]imidazo[1,2-d][1,4]oxazepines were developed by an efficient 7-exo-dig regioselective hydroamination of 2-(2-(prop-2-yn-1-yloxy)phenyl)-1H-benzo[d]imidazole in the presence of potassium carbonate in DMF at 90°C. © 2017 Wiley Periodicals, Inc.
