Abstract
An efficient enantioselective addition of an array of arylboronic acids to various β-nitrostyrenes is catalyzed by a novel and reactive rhodium-diene catalyst and provides β,β-diarylnitroethanes in very good yields with excellent enantioselectivities. Additions to 2-heteroarylnitroolefins and 2-cycloalkylnitroolefins similarly provide the desired products with high enantioselectivities and yields.
