Pot-economic synthesis of N-aryl acridones was performed with 2-aminobenzophenones and aryl boronic acids as starting materials. Cu-catalyzed chelation-assisted oxidative C–N cross-coupling reactions were well merged with the following intra-molecular oxidative dehydrogenative C–H amination reactions under an air atmosphere. The use of reagent capsules can further resolve the compatibility problem of reagents and simplify the operational process, providing a more straightforward access to the target products.

A copper-catalyzed approach for the synthesis of N-aryl acridones via sp2 C-H bond amination using air as oxidant under neutral conditions is disclosed. This reaction not only provides a complementary method for synthesizing medicinally important acridones, but also offers a new strategy for sp2 C-H bond amination.
