| Abstract: | A novel optically active bisphosphine ligand CDP containing a C2-symmetric cyclobutane ring was prepared from an enantiopure anti head-to-head coumarin dimer. CDP was successfully applied to the rhodium-catalyzed asymmetric hydrogenation of arylenamides, affording the corresponding amides up to 93% e.e. |
