摘要:Palladium-Catalyzed Suzuki-Miyaura Coupling Of N-Benzenesulfonyl-3,4-Dibromopyrrole With A Variety Of Arylboronic Acids Gave The Corresponding 3,4-Diarylpyrroles In High Yields. The 3,4-Differentially Arylated Pyrroles Could Also Be Prepared By Stepwise Cross-Coupling Approach. The Total Syntheses Of Lamellarins O,P,Q,And R Have Been Achieved By Using The Cross-Coupling And The Directed Lithiation As Key Reactions. (C) 2007 Elsevier Ltd. All Rights Reserved.
