A RuPHOX−Ru catalyzed asymmetric hydrogenation of γ‐keto acids has been developed, affording the corresponding enantiopure γ‐lactones in high yields and with up to 97% ee. The reaction could be performed on a gram scale with a relatively low catalyst loading (up to 10000 S/C) under the indicated reaction conditions and the resulting products can be transformed to several enantiopure building blocks
已开发出RuPHOX-Ru催化的γ-酮酸不对称氢化反应,可提供高收率和高达97%ee的相应对映体纯γ-内酯。该反应可以在指定的反应条件下以相对较低的催化剂负载量(最高10000 S / C)以克为单位进行,所得产物可以转化为几种对映纯结构单元,生物活性化合物和对映纯药物。
