Abstract

An efficient and facile reaction of quinazoline-3-oxides with primary amines provides a broad range of quinazolin-4(3H)-ones under metal-free and mild reaction conditions employing tert-butyl hydroperoxide as the oxidant. Remarkably, a precursor for the synthesis of bioactive evodiamine and rutaempine was conveniently obtained in good yield.
