Dynamic kinetic resolution of various α-amido-β-keto phosphonates via asymmetrichydrogenation proceeded efficiently to give the corresponding β-hydroxy-α-amido phosphonates in high diastereo- and enantioselectivities (up to 99:1 syn/anti, 99.8% ee). The addition of catalytic amounts of CeCl3·7H2O is necessary to achieve both good selectivity and catalytic efficiency under mild reaction conditions
