  • Efficient syntheses of 25,26-dihydrodictyostatin and 25,26-dihydro-6-<i>epi</i>-dictyostatin, two potent new microtubule-stabilizing agents

    The dictyostatins are powerful microtubule-stabilizing agents that have shown antiproliferative activity against a variety of human cancer cell lines. Two highly active analogs of dictyostatin, 25,26-dihydrodictyostatin and 25,26-dihydro-6-epi-dictyostatin, were prepared by a new streamlined total synthesis route. Three complete carbon fragments were prepared to achieve maximum convergency. These were coupled by a Horner–Wadsworth–Emmons reaction sequence and an esterification. A late stage Nozaki–Hiyama–Kishi reaction was then used to form the 22-membered macrolide. The stereoselectivity of this reaction depended on the configurations of the nearby stereocenter at C6.

    dictyostatins是一类强效的微管稳定剂,已显示出对多种人类癌细胞系的抗增殖活性。dictyostatin的两个高活性类似物,25,26-二氢dictyostatin和25,26-二氢-6-epi-dictyostatin,通过一条新的简化全合成路线制备。为了实现最大的汇聚性,制备了三个完整的碳片段。这些碳片段通过Horner–Wadsworth–Emmons反应序列和酯化反应耦合。然后使用晚期Nozaki–Hiyama–Kishi反应形成22-元大环内酯。这种反应的立体选择性取决于C6附近立体中心的构型。

    A formal convergent synthesis of dictyostatin from (R)‐Roche ester is described. Synthetic highlights include a Ni‐catalyzed Nozaki–Hiyama–Kishi coupling between an aldehyde and a Z vinyl iodide to assemble the two main fragments, a diastereoselective Myers alkylation, a stereoselective Evans aldolization, two asymmetric Duthaler crotyltitanations, and a stereoselective Pd‐catalyzed Marshall allenylindium

    promoted by the standard second-generation Grubbs-Hoveyda catalyst (GH-II), while a new fluorous GH-II catalyst is used for separation and recovery in gram-scale reactions. The transformation is featured in a rapid synthesis of the bottom fragments of the potent anticancer agents (-)-dictyostatin and 6-epi-dictyostatin.

    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
