资源简介:
A highly efficient copper-catalyzed aerobic oxidative intramolecular C–H amination has been developed using substituted 2-(1H-imidazol-1-yl)-N-alkylbenzenamines as the starting materials, and the corresponding imidazobenzimidazole derivatives were obtained in excellent yields. This is an economical and practical method for the construction of N-heterocycles.
