from 3-hydroxybenzotrifluoride. The route is based upon a cuprate-mediated coupling of the single enantiomer vinyl iodide 13 and the tricyclic ketone 5, of high stereochemical purity, to yield the single isomer bicyclic ketone 15. A Baeyer−Villiger oxidation provides the lactone 16 as a crystalline solid, thus limiting the need for chromatographic purification. DIBAL-H reduction, Wittig reaction, esterification
描述了抗青光眼剂曲伏前列素 2 的商业合成。总共需要 22 个合成步骤来提供单一对映异构体前列腺素,最长的线性序列是从 3-羟基苯并三氟化物开始的 16 个步骤。该路线基于铜酸盐介导的高立体化学纯度的单一对映异构体碘乙烯 13 和三环酮 5 的偶联,以产生单一异构体双环酮 15。Baeyer-Villiger 氧化提供作为结晶固体的内酯 16 ,从而限制了色谱纯化的需要。DIBAL-H 还原、Wittig 反应、酯化和甲硅烷基脱保护完成曲伏前列素的合成。
