A direct one-pot copper-catalyzed oxidative C–C bond cleavage route to the synthesis of pyridoquinazolinones is described. This one-pot strategy involves a copper-catalyzed C–N coupling followed by concomitant C(sp3)–H oxidation and amidation via oxidative C–C bond cleavage under an O2 atmosphere to deliver the target molecules in high yields.
