A novel method for the stereoselective preparation of iodohydrins and epoxides from stereogenic vicinal diols is described. This new high-yield methodology consists of the conversion of thionocarbonates such as 12 to the primary iodo derivative 14 with complete regiocontrol. Deprotection of the secondary alcohol derivative in 14 gives the corresponding synthetically versatile iodohydrin 16, which is
描述了一种从立体发生的邻位二醇立体选择制备碘代醇和环氧化物的新方法。这种新的高产率方法包括在完全区域控制的情况下将硫代碳酸酯(如12)转化为主要的碘代衍生物14。14中仲醇衍生物的脱保护得到相应的合成通用的碘醇16,其被转化为环氧化物17。该方法已应用于复杂的四元醇29和34。在二醇的情况下,以一锅法反应方便地以高收率进行转化。
