Abstract

An efficient copper-catalyzed approach to quinazolinone derivatives has been developed, and the protocol uses cheap and readily available substituted 2-halobenzamides and (aryl) methanamines as the starting materials as well as economical and environmentally friendly air as the oxidant. This can be the first example of constructing N-heterocycles via sequential Ullmann-type coupling under air and aerobic oxidative C− H amidation.
