The new chiral diphosphine ligand [(5,6), (5%,6%)-bis(1,2-ethylenedioxy)biphenyl-2,2%-diyl]bis(diphenylphosphine) (Bisben-zodioxanPhos) has been successfully prepared and used in ruthenium-catalyzed asymmetric hydrogenation of 2-(6%-methoxy-2%naphthyl)propenoic acid and b-keto esters with high enant
