Primary allyl alcohols are converted into allyltributylstannanes in a one-pot operation. It entails (i) deprotonation with BuLi, (ii) sulfonylation with mesyl chloride, and (iii) nucleophilic substitution by LiSnBu3. Conversions are quantitative with isolated yields ranging from 70% to 100%. If the starting allyl alcohol contains a stereogenic double bond its configuration is retained.
首先烯丙基醇在一步操作中被转化为
烯丙基三丁基锡烷。该过程包括(i)使用丁基
锂进行去质子化,(ii)用甲
磺酰氯进行砜化,以及(iii)通过三
丁基锡化
锂进行亲核取代。转化率是定量的,分离产率从70%到100%不等。如果初始的烯丙基醇含有手性双键,其构型将得以保持。
