Rh(III)-Catalyzed [4 + 2] Spiroannulation of 2-Phenylbenzimidazoles with Isomerizable 3-Methylmaleimides: Synthesis of Spiro-Fused Benzimidazoisoquinoline Succinimides

Abstract A Rh(III)-catalyzed exclusive [4 + 2] cascade cyclization of 2-phenylbenzimidazoles with 3-methylmaleimides for the synthesis of spiro-fused benzimidazoisoquinoline succinimides via C–H activation is reported. The detailed mechanistic study revealed that the reaction pro...
