The N-Aryl Aminocarbonyl ortho-Substituent Effect in Cu-Catalyzed Aryl Amination and Its Application in the Synthesis of 5-Substituted 11-Oxo-dibenzodiazepines

Double amination of ortho-substituted aryl bromides proceeded under mild conditions to afford 5-substituted 11-oxo-dibenzodiazepines, which revealed that there is a strong ortho-substituent effect caused by N-aryl aminocarbonyl groups during copper-catalyzed aryl amination.
