  硫脲衍生物作为抗微生物剂和抗病毒剂的设计，合成和评价

  摘要：

  背景：细菌对药物的耐药性发展迅速，因此严重限制了抗生素的有效性。 方法：合成，表征和评价了一系列硫脲衍生物的体外抗菌，抗真菌和抗病毒活性。 结果：通过元素分析和光谱分析证实了新合成化合物的结构。生物学结果表明，某些目标化合物具有与参考药物相当的抗微生物和抗病毒活性。结构-活性关系研究表明，硫脲核的Ar1处的邻氯或氟取代的苯基和Ar2处的取代的吡啶基对其体外抗菌和抗HIV活性至关重要。尤其是，化合物8和10与本研究报道的其他合成PET衍生物相比，对测试的细菌，真菌和病毒株显示出更好的活性。 结论：这些结果提供了令人鼓舞的线索，可用于开发新型有效的抗病毒和抗菌药物。

  α-氰基膦酸酯是霍纳-维蒂希反应的有用试剂，是在无溶剂条件下使用氯化胆碱-氯化锌低共熔溶剂（DES）作为催化剂合成的。这只是有关这些化合物合成的第二份报告。在之前的报告中，二乙基三甲基硅基亚磷酸酯被用作试剂，TiCl 4作为催化剂，而在本研究中，试剂（三苯基膦）和催化剂（氯化胆碱-氯化锌DES）都更便宜、更容易获得，并且比之前工作中使用的危害更小。此外，该过程涉及β-硝基苯乙烯和两当量亚磷酸三苯酯之间的有趣级联反应，通过新的合成路线产生所需的产物。该产品除了在制备α,β-不饱和腈的合成应用外，还可用于制药和农业工业。使用 20 mol% DES，在 80 °C 下，反应在 6 小时内完成。纯化后合成了 10 种不同的 β-硝基苯乙烯，产率为 55-87%。含有给电子基团的β-硝基苯乙烯显示出更高的产率。当使用带有吸电子取代基的脂肪族或杂芳香族硝基烯烃或β-硝基苯乙烯时，反应失败。最后，提出

The system was used to effect nucleophilic difluoromethylation of ketones and nitro alkenes. The reaction efficiency is believed to be associated with Lewis acidic activation of the substrates by a silylium species formed upon generation of the phosphorus ylide.
