    Abstract: A process is disclosed for reducing amino acids and derivatives thereof Compounds of formula (I), in which n=0 or 1 and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 have the meanings given in the description, are reduced to the corresponding amino alcohols of formula (II): the formula (I) compounds are converted in a first step, in at least one alcohol and with the addition of acid and heat to an ester, this process producing a reaction mixture containing the ester; the ester is converted in a second reaction step with alkali or alkaline earth borohydride to compounds of formula II. By specifying that the second step be carried out without isolating the ester from the reaction mixture and by using alkali or alkaline earth borohydrides which are not activated, the invention facilitates the production from amino acids and their derivatives of the correponding alcohols in a simple "single vessel" process, with high yields and in such a way as to preserve a given centre of chirality.

    Abstract: A process is provided for preparing an L-.alpha.-amino acid from a 5(4H)-oxazolone precursor. The precursor is subjected to a two-step process sequence in which the precursor is first contacted with a methanolytically active lipase in the presence of methanol in a non-polar solvent to enantioselectively solvolyze the precursor and produce an intermediate optically active methyl ester of the desired .alpha.-amino acid. This ester is then contacted with a protease in the presence of water to enantioselectively cleave the ester and accomplish an enzymatic kinetic resolution to prepare the product L-.alpha.-amino acid in high optical purity.
