    通过基于Stille偶联的策略进行埃博霉素E和相关侧链修饰类似物的全合成。
    摘要:
    已利用Stille偶联策略完成了从乙烯基碘7和噻唑-锡烷8h合成埃博霉素E的全过程。使用闭环复分解(RCM)由三烯15制备中心核心片段7及其反式异构体11,随后将其与多种替代的锡烷偶联以提供埃坡霉素类似物18a-o和19a-o的文库。然后使用Stille偶联方法从关键的大内酯中间体24制备埃博霉素B类似物,该中间体本身是通过基于大内酯化的策略合成的。

    Sets of Aldolase Antibodies with Antipodal Reactivities. Formal Synthesis of Epothilone E by Large-Scale Antibody-Catalyzed Resolution of Thiazole Aldol
    摘要:
    Three monoclonal aldolase antibodies, generated against beta-diketone hapten by reactive immunization, catalyzed rapid and highly enantioselective retro-aldol reactions of ent-8a-k, providing optically pure 8a-k by kinetic resolution. Compounds (+/-)-8a, (+/-)-8g, and (+/-) 8k have been resolved in multigram quantities using 0,003, 0.005, and 0.0004 mol % antibody catalysts, respectively. Resolved compounds 8a-k are useful synthons for the construction of epothilones A-E (2-6) and their analogues. Here, a formal synthesis of epothilone E, 6 has been achieved starting from compound 8g.

  • Catalytic Antibody Route to the Naturally Occurring Epothilones: Total Synthesis of Epothilones A-F
    作者:Subhash C. Sinha、Jian Sun、Gregory P. Miller、Markus Wartmann、Richard A. Lerner
    DOI:10.1002/1521-3765(20010417)7:8<1691::aid-chem16910>3.0.co;2-9
    日期:2001.4.17
    synthesized starting from enantiomerically pure aldol compounds 9-11, which were obtained by antibody catalysis. Aldolase antibody 38C2 catalyzed the resolution of (+/-)-9 by enantioselective retro-aldol reaction to afford 9 in 90% ee at 50 % conversion. Compounds 10 and 11 were obtained in more than 99% ee at 50% conversion by resolution of their racemic mixtures using newly developed aldolase antibodies
    天然存在的埃坡霉素已从对映异构纯的羟醛化合物 9-11 开始合成,这些化合物是通过抗体催化获得的。醛缩酶抗体 38C2 通过对映选择性逆醛醇反应催化 (+/-)-9 的拆分,以 50% 转化率提供 9 in 90% ee。通过使用新开发的醛缩酶抗体 84G3、85H6 或 93F3 拆分其外消旋混合物,化合物 10 和 11 的转化率为 99% 以上,转化率为 50%。化合物 9、10 和 11 以数克的量进行拆分,然后通过复分解过程转化为埃坡霉素,该过程由 Grubbs 催化剂催化。
