  Development and Scale-up of an Organocatalytic Enantioselective Process to Manufacture (S)-Pregabalin

  摘要：

  Herein is reported the development of a new process to manufacture (S)-pregabalin. The method comprises six steps, run under the catalysis of a recyclable polymer bound phase transfer catalyst, and afforded (S)-pregabalin in overall 54% yield, starting from building blocks acetylacetone, isovaleraldehyde, and nitromethane.

  The invention relates to the preparation of gamma amino acids of formula (I) and pharmaceutically acceptable salts, solvates and prodrugs thereof, and to intermediates used for their preparation. (formula I) wherein R1 is selected from an alkyl group, an alkenyl group, an alkynyl group and a cycloalkyl group, each of which may be optionally substituted and * denotes a chiral centre. In particular, the present invention provides an efficient synthesis of (S)-pregabalin which is suitable for carrying out on an industrial scale.

  该发明涉及制备公式(I)的γ-氨基酸及其药学上可接受的盐、溶剂合物和前药，以及用于其制备的中间体。(公式I)其中R1选自烷基、烯基、炔基和环烷基，每种基团均可选择性地被取代，*表示一个手性中心。特别是，本发明提供了(S)-普瑞巴林的高效合成方法，适用于工业规模生产。
