title: IrIII-Catalyzed One-Pot Cascade Synthesis of Pentacyclic-Fused Carbazoles from Indoles and Diazoes.
abstract: A highly efficient IrIII-catalyzed cascade cyclization of indoles and diazoes giving access to unique pentacyclic-fused carbazoles has been developed. This novel strategy expanded the application scope of coupling partners to take diazo compounds as a C2 source, and two new cycles, three new C-C and one new C-N bonds were formed in one-pot.
