摘要：
A rhodium(III)-catalyzed amidation between benzoic acids and isocyanates via direct functionalization of an ortho C-H bond followed by intramolecular cyclization is described. This cascade cyclization affords N-substituted phthalimides in one step in 26-91% yields. The reaction is highly atom-economical, since no theoretical waste except for water is generated in the reaction.
