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.
本发明涉及制备公式(I)的γ-氨基酸及其药学上可接受的盐、溶剂化物和前药,以及用于它们制备的中间体。(公式I)其中R1选自烷基、烯基、炔基和环烷基,每个基团均可选择性地被取代,*表示手性中心。特别地,本发明提供了一种适用于工业规模的(S)-pregabalin的高效合成方法。
