All stereoisomers of goniodiol were synthesized from yeast-reduction products. The C-6 chiral centers were converted from the chiral centers of the yeast-reduction products. Stereoselective conversion of the alkene, which had been prepared from the yeast-reduction product, to glycol constructed the C-7 and C-8 stereochemistry. (+)-Goniodiol and 7-epi-(+)-goniodiol showed the highest antibacterial activity (MIC, 3.1 mm) against Yersinia intermedia.
贡碘醇的所有立体异构体都是由酵母还原产物合成的。C-6 手性中心由酵母还原产物的手性中心转化而来。由酵母还原产物制备的烯烃立体选择性地转化为乙二醇,构建了 C-7 和 C-8 立体化学结构。(+)-冈碘二醇和 7-表-(+)-冈碘二醇对中间耶尔森菌的抗菌活性最高(MIC,3.1 毫米)。
