Natural 12-hydroxyheptadecatrienoic acid (12-HHT) with an S configuration was synthesised by a Suzuki–Miyaura coupling of C10–C17 iodo alcohol with C1–C9 vinylborane. The iodo alcohol was synthesised by utilising Sharpless asymmetric epoxidation of the corresponding trimethylsilyl alcohol. The method yielded more than 100 mg of 12-HHT. Similarly, syntheses of 5,6-dihydro- and 14,15-dehydro derivatives
通过S10 -C17碘醇与C1-C9乙烯基硼烷的Suzuki-Miyaura偶联合成具有S构型的天然12-羟基十七碳三烯酸(12-HHT)。通过利用相应的三甲基甲硅烷基醇的Sharpless不对称环氧化来合成碘醇。该方法产生了超过100毫克的12-HHT。同样,分别以立体选择性的方式完成了12-HHT的5,6-二氢-和14,15-脱氢衍生物的合成,分别称为HHD和HHTE。
