solution is reported to the classic unsolved problem of stereoselective synthesis of all-E oligoprenols, such as E-farnesylfarnesol, by a cationic coupling analogous to the biosynthetic pathway. The simplicity and efficacy of the method, which is outlined in Scheme 1, are demonstrated by the synthesis of a series of all-E oligoprenols from C(20) to C(35) in uniformly excellent overall yield. The success
据报道,通过类似于生物合成途径的阳离子偶联,解决了立体选择性合成全 E 低聚戊二烯醇(例如 E-法呢基法呢醇)的经典未解决问题。该方法的简单性和有效性在方案 1 中概述,通过合成一系列从 C(20) 到 C(35) 的全 E 低聚异戊二烯醇以一致优异的总产率得到证明。该方法的成功不仅归功于形成低聚异戊二烯链的高度 E-立体选择性 CC 偶联,还归功于烯丙基仲硅烷和 E-低聚戊二烯缩醛的有效合成以及选择性烯丙基脱甲氧基化反应的发展。
