One-pot, diversity-oriented synthesis of aryl-substituted benzoxacycles including benzofuran, coumarin, and benzoxazepine

A one-pot method for the synthesis of benzoxacycles including benzofuran, coumarin, benzoxazepine, and benzoxazocine from a common synthetic intermediate was established. Benzoxacycles are privileged structures in medicinal chemistry and have featured in several clinically used drugs. The synthesis of a benzofuran containing an aryl substituent was accomplished using potassium carbonate and sodium hydride. The one-pot synthesis of coumarin was also carried out using trans-decalin as the solvent. The optimized conditions for the one-pot synthesis of benzoxazepine can also be applied to the synthesis of benzoxazocine.
