efficient and applicable I2-catalyzed intramolecular dehydrogenative C-O/C-N coupling reaction via activating the C-H bond adjacent to the N atom has been developed to provide dozens of substituted benzoxazinones (31 examples) and quinazolinones (5 examples) in good to excellent yields (up to 98%). This one-pot methodology has significant advantages, including metal-free process, broad substrate scope,
