  Process for the preparation of enantiomerically enriched compounds

  摘要：

  制备对映富集的氨基醛和氨基醇的过程，其中对应的对映富集的氨基腈在氢气、氢化催化剂（最好是Pd催化剂）和矿酸存在下进行加氢。用于制备氨基醛时，最好在氢压力在0.1至2兆帕之间，特别是在0.5至1兆帕之间。氨基醛最好以化学和构型稳定的衍生物形式分离。用于制备氨基醇时，最好在加氢的部分时间内氢气的压力在2至10兆帕之间，特别是在4至6兆帕之间。在一种首选实施方式中，氢气压力最初在0.5至2兆帕之间，随后，在大部分腈起始物质被转化后，氢气压力增加到2至10兆帕之间的值。对映富集的腈起始物质可以通过酶解、经典分离、通过优先结晶分离、对映异构合成、催化不对称合成或氨基酸酰胺的脱水制备等方法制备。

  Process for the preparation of enantiomerically enriched amino aldehydes and amino alcohols, wherein a corresponding enantiomerically enriched amino nitrile is subjected to hydrogenation in the presence of hydrogen, a hydrogenation catalyst, preferably a Pd-catalyst and a mineral acid. For the preparation of an amino aldehyde hydrogen preferably is present at a hydrogen-pressure between 0.1 and 2 MPa, in particular between 0.5 and 1 MPa. The amino aldehyde preferably is isolated in the form of a chemically and configurationally stable derivative. For the preparation of an amino alcohol, preferably at least during part of the hydrogenation hydrogen is present at a hydrogen-pressure between 2 and 10 MPa, in particular between 4 and 6 MPa. In a preferred embodiment the hydrogen-pressure initially is between 0,5 and 2 MPa and subsequently, after most of the nitrile starting material is converted, the hydrogen pressure is increased to a value between 2 and 10 MPa. The enantiomerically enriched nitrile starting material may a.o. be prepared by enzymatic resolution, classical resolution, resolution via preferential crystallization, diastereomeric synthesis, catalytic asymmetric synthesis or dehydratation of amino acid amides.

Process for the preparation of enantiomerically enriched amino aldehydes and amino alcohols, wherein a corresponding enantiomerically enriched amino nitrile is subjected to hydrogenation in the presence of hydrogen, a hydrogenation catalyst, preferably a Pd-catalyst and a mineral acid.
