An enantioselective asymmetric total synthesis of (+)-vittatalactone has been accomplished employing enzymatic desymmetrization approach to create two methyl chiral centres. Other key steps involved are Wittig reaction, Evan's asymmetric alkylation, hydroboration, TEMPO-BAIB-mediated selective oxidation of 1,3-diol and lactonization mediated by p-toluenesulfonyl chloride. The total synthesis was achieved
(+)-vittatalactone 的对映选择性不对称全合成已经使用酶促去对称化方法来创建两个甲基手性中心。其他关键步骤包括 Wittig 反应、Evan 的不对称烷基化、硼氢化、TEMPO-BAIB 介导的 1,3-二醇选择性氧化和对甲苯磺酰氯介导的内酯化。全合成通过线性合成序列实现,总产率为11.8%。
