Development of chiral phosphorus ligands has drawn intensive interest owing to their significant role in transition-metalcatalyzed asymmetric reactions.[1] Catalytic asymmetric hydrogenation has been widely used as a practical and efficient method in the synthesis of chiral molecules.[2] Although excellent enantioselectivities have been obtained by using benchmark ligands such as dipamp (1, 2-ethanediylbis [(2-methoxyphenyl) ...
