Horner–Wadsworth–Emmons reaction, 16 reacted with aldehyde 22, which contained the vicinal anti-Me–OH pattern and a vinyl iodide function, to provide the C1–C13 part of pladienolide B. After Shiina macrolactonization, reduction of the enone 26 gave the core structure 27. A Stille cross-coupling of vinyl iodide 27 with tributylphenylstannane eventually furnished analogue 30.

芳樟醇(6)开始,末端的分化和通过醛醇缩合反应的链扩展导致了酮
膦酸酯16(C1-C8结构单元)。在Horner-Wadsworth-Emmons反应中,16与醛22反应,该醛具有邻位的抗Me-OH模式和
碘乙烯功能,提供了普拉二烯内酯B的C1-C13部分。图26给出了核心结构27。
乙烯基碘化物27与
三丁基苯基锡烷的Stille交叉偶联最终提供了类似物30。
