Sequential activation of a-bonds : Intermolecular cascade annulation with migration and remote functionalization
We demonstrate a new catalytic property of the lanthanide compound CeCl3 center dot 7H(2)O which sequentially activates N-H, sp(2) C-H and sp(3) C-H sigma-bonds at ambient temperature. The powerful catalyst enables selective C-C and C-N bond-forming intermolecular cascade annulation between enamines and diary1-1,2-diketone to afford functionalized 3,3-diaryl-3-pyrrolin-2-ones involving migration of an aromatic ring. We have also initiated a new multicomponent strategy utilizing readily available and inexpensive precursors and environmentally benign CeCl3 center dot 7H(2)O as an efficient catalyst under benign reaction conditions towards direct synthesis of several N-heterocycles including pentasubstituted 2-pyrrolinones and pyrroles. These observations provide new prospects and perspectives in sigma-bond activation process for easy access to functional molecules.
