Rhodium complexes of (R)-Me-CATPHOS and (R)-(S)-JOSIPHOS form a complimentary pair of catalysts for the highly efficient asymmetric hydrogenation of (E)- and (Z)-beta-aryl-beta-(enamido)phosphonates, in each case giving excellent yields and ee’s in excess of 99%, the highest to be reported for this class of substrate.
