The key reactions involved are the Hinsberg-type synthesis of dimethyl N-benzyl-3,4-dihydroxypyrrole-2,5-dicarboxylate (6) followed by palladium-catalyzed Suzuki-Miyaura coupling of its bis-triflate derivative (7). The N-benzyl protecting group of the resulting 3,4-diarylpyrrole-2,5-dicarboxylates (8) is cleanly removed under hydrogenolytic or solvolytic conditions., HETEROCYCLES, 77 (2), pp.1105-1122; 2009}, pages = {1105--1122}, title = {A GENERAL METHOD FOR THE SYNTHESIS OF N-UNSUBSTITUTED 3,4-DIARYLPYRROLE-2,5-DICARBOXYLATES}, volume = {77}, year = {2009} }
