The alpha-Arylation of Amines by the Catalytic, Enantioselective Addition of Arylboronic Acids to N-Boc Imines

Ellman and co-workers have reported the first rhodium-catalyzed, enantioselective addition of arylboronic acids to N-Boc imines. Cleavage of the initially formed addition product with a mild base under anhydrous conditions leads to the corresponding alpha-arylated N-Boc amines. Read More
