and environmental-friendly method for the construction of acridone derivatives with isatins and arynes was described. The isatins underwent a ring expansion process oxidized by O2 in the air and a broad scope of acridones in moderate to good yields were obtained. Baeyer-Villiger-type oxidation and intermolecular-nucleophilic addition were included, and no extra oxidant except O2 was needed.
