Enantiopure (R)-3-hydroxy-5-oxohexanoic acid esters have proven to be useful intermediates in the synthesis of the side chain of statins, in view of the recently described preparation of rosuvastatin and other statins through aldol reactions. Herein, an improved synthesis of these intermediates, by combining chemical and enzymatic reactions, is described. In particular, the selective reduction of a
鉴于最近描述的通过羟醛反应制备罗苏伐他汀和其他他汀类药物,Enantiopure (R)-3-羟基-5-氧代己酸酯已被证明是合成他汀类药物侧链的有用中间体。在此,描述了通过结合化学和酶促反应来改进这些中间体的合成。特别是,δ-缩酮β-酮酯的选择性还原被确定为获得具有令人满意的光学纯度的衍生物用于合成他汀类药物的关键步骤。
