Synthesis of Phenanthridines via Palladium-Catalyzed Annulation of 2-Iodobenzimines with 2-Halobenzoic Acids
A palladium-catalyzed decarboxylative annulation reaction of 2-iodobenzimines with 2-halobenzoic acids for the synthesis of phenanthridine scaffolds has been developed. Density functional theory calculations revealed that in the presence of the KOAc additive, this annulation reaction proceeds via Pd(II) transmetalation pathway rather than the oxidative Pd(IV) formation pathway. The base Cs2CO3 plays a crucial role in C−H bond activation, which is the rate-determining step.
