摘要
A convenient and effective method for Pd-catalyzed cross-dehydrogenative C(sp(2))-H/N-H couplings to synthesize fused N-heterocyclic benzimidazoquinazoline derivatives was developed. The reaction employs Pd(OAc)(2) as the catalyst and Cu(OAc)(2) or O-2 (from the air) as the terminal oxidant. The strategy uses simple and easily accessible substrates. This method provides a route to azole-fused heterocycles.
