A new copper-catalyzed regioselective cross-dehydrogenative coupling of coumarins with benzylic C-sp3-H bonds has been developed. This reaction provides direct access to a wide range of 3-benzylcoumarins in moderate to good yields. The protocol was also extended successfully to other heterocyclic compounds, such as quinolinones.
