A copper-catalyzed method for the synthesis of imidazo[1,2-a]pyridines with aminopyridines and nitroolefins using air as oxidation agent in a one-pot procedure has been developed. In this process, the reaction appears to be very general and suitable for construction of a variety of imidazo[1,2-a]pyridines.
开发了一种铜催化的一锅法,以空气为氧化剂,与氨基吡啶和硝基烯烃合成咪唑并[1,2- a ]吡啶。在此过程中,反应似乎非常普遍,适合于构建各种咪唑并[1,2- a ]吡啶。
