Abstract
Abstract A chiral hydroxyl bisphospholane, 1,2-bis[(2 S ,3 S ,4 S ,5 S )-3,4-dihydroxyl-2,5-dimethylphospholanyl]benzene ( 4 ), was synthesized from readily available d -mannitol. Its Rh(I) complex catalyzes asymmetric hydrogenation of dehydroamino acids and their ester derivatives with excellent enantioselectivities (98 to >99% ee).
