A process for preparing a non-racemic aminoalcohol is provided. The process includes the step of contacting a chiral alpha-amino carbonyl compound and hydrogen, in the presence of a non-racemic hydrogenation catalyst, at a temperature, pressure and for a length of time sufficient to produce the non-racemic aminoalcohol. In a preferred embodiment, the process can be described by the reaction scheme:
where R is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl or hetereoaryl group; and E can be hydrogen, COOR, CONHR, CONR

, alkyl, substituted alkyl, aryl, substituted aryl or hetereoaryl group.
提供一种制备非对映异构氨基醇的方法。该方法包括以下步骤:在非对映异构氢化催化剂的存在下,将手性α-氨基羰基化合物和氢接触,在足够的温度、压力和时间条件下,产生非对映异构氨基醇。在一种首选实施例中,该方法可以通过以下反应方案描述:其中R为氢、烷基、取代烷基、芳基、取代芳基或杂环芳基;E可以是氢、COOR、CONHR、CONR2、COOH、COR、CN、NO2、烷基、取代烷基、芳基、取代芳基或杂环芳基。
