The preparation of enantiomerically pure 2-propanoyl-1,3-propanediol derivatives, key intermediates in our studies on total synthesis of the potent antitumor compound Kazusamycin A are described. After various enzymatic protocols for desymmetrization of the prochiral diol were studied, it was found that these compounds could be prepared in 97–98% ee by means of an enzymatic kinetic resolution.
描述了对映体纯的2-丙酰基-1,3-丙二醇衍生物的制备方法,这是我们对有效的抗肿瘤化合物卡祖霉素A进行全合成研究的关键中间体。在研究了多种用于手性二醇去对称化的酶促方案后,发现可以通过酶促动力学拆分以97–98%ee的方式制备这些化合物。
