We report here a simple and convenient route for the stereoselective synthesis of (R)-(−)- and (S)-(+)-homocitric acid lactones, which play very important roles in biochemistry. The method involves only three steps, starting from the readily available methyl 3-iodopropionate and d-malic acid or l-malic acid, respectively. The stereoconfiguration of the target molecules has been achieved via a self-regeneration
我们在这里报告了一种简单而便捷的路线,用于(R)-(-)-和(S)-(+)-高纯酸内酯的立体选择性合成,它们在生物化学中起着非常重要的作用。该方法仅涉及三个步骤,分别从容易获得的3-碘丙酸甲酯和d-苹果酸或l-苹果酸开始。目标分子的立体构型已通过自再生方法实现,其非对映选择性超过98%,并且与以前的方法相比,产率得到了显着提高。
