A New Chiral Rhodium(I) Complex of (2 R ,3 R )‐2,3‐Bis(diphenylphosphino)butane for Asymmetric Hydrogenations Rhodium(I) complexes of the new chiral ligand (2 R ,3 R )‐2,3‐bis(diphenylphosphino)butane ( 4 ) — which is easily prepared from natural tartaric acid — hydrogenate α‐(acylamino)acrylic acids to natural ( S )‐acylamino acids in high chemical (95 – 100%) and optical (80 – 100%) yields.
