A simple, practical, and highly efficient copper‐catalyzed one‐pot synthesis of imidazo/benzoimidazoquinazolinones has been developed. The procedure is based on a sequential copper‐catalyzed Ullmann‐type N‐arylation and aerobic oxidative intramolecular CH amidation. This method should provide a new and useful strategy for construction of N‐heterocycles.
