    provide a third new synthesis based on esterification and Nozaki-Hiyama-Kishi reaction. This was used to prepare the target dihydro analogues and the natural product. All of the syntheses are streamlined because of their high convergency. The work provided several new analogues of dictyostatin, including a truncated macrolactone and a C10 E-alkene, which were 400- and 50-fold less active than (-)-dictyostatin
    dictyostatins 是一类很有前景的潜在抗癌药物,因为它们是强大的微管稳定剂,但其化学结构的复杂性严重阻碍了它们的进一步发展。在合成和药物化学分析的基础上,16-desmethyl-25,26-dihydrodictyostatin 及其 C6 差向异构体被选为潜在有效但可用的 dictyostatin 类似物,并开发了三种新的合成方法。涉及乙烯基锂加成和大环化的相对经典的合成让位于基于酯化和闭环复分解反应的更新和更实用的方法。最后,结合这两种方法的各个方面以提供基于酯化和 Nozaki-Hiyama-Kishi 反应的第三种新合成。这用于制备目标二氢类似物和天然产物。由于它们的高收敛性,所有的合成都是流线型的。这项工作提供了几种新的 dictyostatin 类似物,包括截短的大环内酯和 C10 E-烯烃,它们的活性分别比 (-)-dictyostatin 低 400 和 50 倍。相比之下,靶向

    An efficient convergent synthesis of the anticancer marine macrolide (−)-dictyostatin is described that proceeds in 4.6% yield over 27 steps. Most of the stereocentres were configured using substrate control, making use of a common building block to install the C12–C14 and C20–C22 stereotriads, with a lactate boron aldol reaction employed to construct a C4–C10 β-ketophosphonate as utilised in the pivotal
