A stereoselective total synthesis of xyolide, a naturally occurring bioactive nonenolide, has been accomplished. The acid fragment of the molecule has been prepared from D‐mannitol and the alcohol fragment from (2Z)‐but‐2‐ene‐1,4‐diol. The synthesis involves the coupling of these two fragments using the Yamaguchi esterification protocol, followed by intramolecular ring‐closing methathesis. The diastereoisomeric
已经完成了自然存在的生物活性壬烯内酯二甲酸酯的立体选择性全合成。该分子的酸片段是由D-甘露醇制备的,而醇片段是由(2 Z)-丁-2-烯-1,4-二醇制备的。合成过程涉及使用Yamaguchi酯化方案将这两个片段偶联,然后进行分子内闭环置换。通过采用Mitsunobu酯化反应,非对映异构醇片段也已用于该合成中。
