An efficient nickel-catalyzed asymmetric hydrogenation of hydrazones to chiral hydrazines has been realized with up to 99 % yield and 99.4 : 0.6 er. Deuterium labelling experiments indicated that the hydrazone substrates undergo imine-enamine tautomerizat

(Figure presented) An enantioselective hydrogenation of hydrazones catalyzed by Rh complexes (Rh-Josiphos or Rh-Taniaphos) has been developed. The protocol can be applied to hydrazones with three different protective groups (Boc, Cbz, and methoxycarbonyl)
