novel and efficient copper-catalyzed cascade method for the synthesis of quinazoline derivatives has been developed. The protocol uses readily available substituted (2-bromophenyl)methylamines and amidine hydrochlorides as the starting materials, inexpensive CuBr as the catalyst, and economical and environment friendly air as the oxidant, and the corresponding quinazoline derivatives were obtained in
开发了一种新型高效的铜催化级联合成喹唑啉衍生物的方法。该方案以易得的取代(2-溴苯基)甲胺和脒盐酸盐为起始原料,以廉价的CuBr为催化剂,以经济环保的空气为氧化剂,以中等至良好的收率获得了相应的喹唑啉衍生物。该过程经历了连续的分子间 N-芳基化、分子内亲核取代和有氧氧化。
