  Studies leading to a total synthesis of epothilones B and D are described. The overall synthetic plan was based on late-stage fragment assembly of two segments representing C(1)-C(9) and C(10)-C(21) of the structure. The C(1)-C(9) fragment was prepared by elaboration of commercially available (2R)-3-hydroxy-2-methylpropanoate at both ends of the three-carbon unit. Introduction of carbons 1-4 containing

  描述了导致全合成埃坡霉素B和D的研究。总体合成计划是基于代表该结构的C（1）-C（9）和C（10）-C（21）的两个片段的后期片段组装。C（1）-C（9）片段是通过在三碳单元的两端精制可商购获得的（2R）-3-羟基-2-甲基丙酸酯制备的。使用非对映选择性地添加β-酮酯二价基团的锡烷对映体以收敛的方式实现了含有宝石二甲基单元的碳原子1-4的引入。对苯二酮酯二价阴离子的对映选择性加成也用于形成C（10）-C（21）亚基的一种形式。但是，带有该亚基的片段组装（使用双分子酯化然后进行闭环复分解）失败了。所以，使用维蒂希反应实现片段组装；随后进行大环内酯化以关闭大环。该方法所需的C（10）-C（21）亚基是使用Corey-Kim反应作为关键元素以有效方式制备的。合成中的其他关键反应包括β-羟基酮的立体选择性SmI（2）还原和戊酸内酯与苯胺的临界打开，这需要大量研究。
