Herein we report a novel palladium-catalyzed oxidative carbonylation reaction for the synthesis of phthalimides with high atom- and step-economy. In our strategy, the imine and H2O, which are generated in situ from the condensation of aldehyde and amine, serve as self-sufficient directing group and nucleophile, respectively. This method provides rapid access to phthalimides starting from readily available materials in a one-pot manner. Various phthalimide derivatives are constructed efficiently, including medicinally and biologically active phthalimide-containing compounds.

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.
