The total synthesis of apoptolidin (1) is reported together with the design, synthesis, and biological evaluation of a number of analogues. The assembly of key fragments 6 and 7 to vinyl iodide 3 via dithiane coupling technology was supplemented by a second generation route to this advanced intermediate involving a Horner-Wadsworth-Emmons coupling of fragments 22 and 25. The final stages of the synthesis
报道了凋亡素 (1) 的全合成以及许多类似物的设计、合成和生物学评价。通过二噻烷偶联技术将关键片段 6 和 7 组装成乙烯基碘化物 3 并辅以第二代路线,该路线包括片段 22 和 25 的 Horner-Wadsworth-Emmons 偶联。合成的最后阶段采用 Stille碘化乙烯 3 和乙烯基锡烷 2 之间的偶联、山口内酯化、许多糖苷化和最终脱保护。开发的合成技术被应用于构建几种类似物,包括 74、75 和 77,它们对肿瘤细胞具有显着的生物活性。
