Yamaguchi reaction to close the macrolactone ring. Some specific biological properties (cytotoxicity, binding to tubulin) have been determined for both macrolides. The E configuration of the C12-C13 olefinic bond seems to be an important feature in determining the cytotoxicity but the precise biological mechanism of the latter still remains to be cleared.
描述了天然存在的细胞毒性大环内酯FD-891及其非天然(Z)-C12异构体的总立体选择性合成。以不对称的羟醛和烯丙基化反应为关键步骤,立体选择性地制备了主碳链的三个片段。然后通过使用两个Julia-Kocienski烯烃连接三个片段和进行Yamaguchi反应以封闭大内酯环来组装该分子。对于这两种大环内酯类药物,已经确定了一些特定的生物学特性(细胞毒性,与微管蛋白的结合)。C12-C13烯键的E构型似乎是确定细胞毒性的重要特征,但后者的确切生物学机制仍有待进一步研究。
