Department of Chemistry, Fudan University, Shanghai 200433, China.

Assembly of N-substituted 1,3-dihydrobenzimidazol-2-ones is achieved starting from methyl o-haloarylcarbamates via a CuI/amino acid catalyzed coupling with amines and subsequent condensative cyclization. A number of functional groups are tolerated by these reaction conditions, including vinyl, nitro, carboxylate, amide, ester, ketone, and silyl ether groups.
