Optically pure (R)- and (S)-3-hydroxybutanoic acid and itshomologues are prepared by the method consisting of the enantioface differentiating hydrogenation of methyl 3-oxoalkanoate to methyl 3-hydroxyalkanoate(80–90% e.e.) over asymmetrically modified nickel catalyst and the preferential crystallization of optically pure 3-hydroxyalkanoic acids from the hydrogenation products as the dibenzylammonium
