Abstract: A Cu(II)-catalyzed domino process involving the carbene N-H insertion, intramolecular aldol-type trapping and unprecedented ring-expansion of oxindole core through C3-selective 1,2-carbonyl migration is described for the synthesis of indolo[3,2- c]quinolinones. This tetracyclic core, having an… read more here.
