A process is disclosed for the enantioselective hydrogenation of olefins of the formula: <IMAGE> (I) where R is hydrogen or C1 to C6 linear or branched alkyl, Z is <IMAGE> where R' is hydrogen or C1 to C6 linear or branched alkyl, -CN, C(NH)OR'' where R'' is C1 to C6 linear or branched alkyl, or -C(O)NH2; and Ar is phenyl or naphthyl unsubstituted or substituted with benzoyl or substituted benzoyl, C1 to C6 linear or branched alkyl, C1 to C6 linear or branched alkoxy, halo, or carboxylic acid or C1 to C6 linear or branched alkyl ester thereof, which comprises contacting said aromatic-substituted olefin with a catalytically effective amount of a ruthenium phosphite complex.
