  康他汀A-4苯并杂环衍生物的（Z）异构体的合成：几种方法的比较研究

  摘要：

  研究了几种制备（Z）三甲氧基苯乙烯衍生物1的方法。在发现Wittig反应导致不满意的结果后，考虑了三种不同的策略：使用DMF / KOH作为氢源的Suzuki偶联与立体定义的单溴烯烃，氢化硅烷化/乙烯基硅烷水解和钯催化的半氢化步骤的组合。我们的研究使我们通过Sonogashira偶联反应制备了一系列二芳基乙炔衍生物，并且发现了无铜的碱性环化反应，从而生成了苯并[ b ]噻吩。1的合成方法的最终选择 强烈依赖于目标化合物，但通常应优先选择避免使用有毒锡还原剂的半氢化反应。

  Synthesis and biological evaluation of novel heterocyclic derivatives of combretastatin A-4

  摘要：

  A novel series of combretastatin A-4 heterocyclic analogues was prepared by replacement of the B ring with indole, benzofurane or benzothiophene, attached at the C2 position. These compounds were evaluated for their abilities to inhibit tubulin assembly: derivative cis 3b, having a benzothiophene, showed an activity similar to those of colchicine or deoxypodophyllotoxine. The antiproliferative and antimitotic properties of cis 3b against keratinocyte cancer cell lines were also evaluated and the intracellular organization of microtubules in the cells after treatment with both stereoisomers of 3b was also determined, using confocal microscopy.

  monobromoalkene, a combination of hydrosilylation/vinylsilane hydrolysis and a palladium-catalyzed semi-hydrogenation step, using DMF/KOH as the hydrogen source. Our studies led us to prepare a series of diarylacetylene derivatives via a Sonogashira coupling reaction, and also to find out a copper-free basic cyclization leading to benzo[b]thiophenes. The final choice for the synthesis method of 1 strongly depends
