Abstract : A highly enantioselective (up to 91% ee) rhodium-catalyzed asym. addition of arylboronic acids has been achieved leading to the challenging dihydro-3-nitronaphthalenes using one equivalent of phosphoramidite ligand to rhodium catalyst. A concise formal asym. synthesis of the dopamine D1 agonist, dihydrexidine was accomplished using the method.
