Abstract A novel method for effecting the inversion of configuration of two and three contiguous carbinol centers in a diol, triol, and tetraol chain, thus affording the opposite enantiomer with ⩾98% e.e., has been developed. The method is based on the sequential formation of a terminal epoxide, Payne rearrangement, and intramolecular lactonization. Application of this methodology to the synthesis
摘要:研究了一种新的方法,该方法可改变二元,三元醇和四元醇链中两个和三个连续的甲醇中心的构型,从而提供对映体的ee约为98%。该方法基于末端环氧化物的连续形成,Payne重排和分子内内酯化。描述了该方法从相同的对映体纯的起始原料合成白三烯A4中间体及其对映异构体,以及蚊子库蚊和其对映异构体的产卵引诱剂信息素的方法1。
