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.In this work, we propose the XO-PBC method, which combines the eXtended ONIOM method (XO) with the periodic boundary condition (PBC) for the description of molecular crystals. XO-PBC tries to
