The cytotoxic marine metabolite harzialactone A has been synthesized stereoselectively starting from phenylacetaldehyde through three different routes. The key steps were: in the first approach Sharpless asymmetric dihydroxylation, in the second approach diastereoselective iodo carbonate preparation, and in the third approach Jacobsen’s hydrolytic kinetic resolution. In all these three schemes the
已经从苯乙醛通过三种不同途径立体选择性地合成了具有细胞毒性的海洋代谢产物harzialactoneA。关键步骤是:在第一种方法中,进行Sharpless不对称二羟基化反应;在第二种方法中,制备非对映选择性碘代碳酸盐;在第三种方法中,Jacobsen水解动力学拆分。在所有这三个方案中,通过使用TEMPO和(二乙酰氧基碘)苯进行高度化学选择性氧化,三醇成功地转化为内酯。 harzialactone A-立体选择性合成-Maruoka烯丙基化-Sharpless不对称二羟基化-立体选择性碳酸碘代制备-Jacobsen水解动力学拆分 该系列的第38部分“天然产物的综合研究”。
