  摘要：

  我们报道了在 AgF 存在下，由杂芳基羧酸和位阻异硫氰酸酯（包括各种氨基酸类似物）一锅法合成N -CF 3杂芳基酰胺（NTFMHA）。该反应的关键是利用游离杂芳基酰氯，而不是其相应的盐酸盐。该方法代表了我们之前工作的补充方法，并且能够对各种以前无法接近的结构进行修饰，包括α-叔胺和N -CF 3修饰的药物。

  library led to the identification of 2,2′‐methylenebis(5‐(4‐bromophenyl)‐4,4‐dimethyl‐2,4‐dihydro‐3H‐pyrazol‐3‐one), a phenyldihydropyrazolone dimer, which shows an in vitro pIC50 value of 5.4 against Trypanosoma cruzi. Initial optimization was done by varying substituents of the phenyl ring, after which attempts were made to replace the phenyl ring. Finally, the linker between the dimer units was varied

  查加斯病正在成为一个世界性问题；目前估计超过六百万人受到感染。目前使用的两种药物，苯并硝唑和硝呋莫司，需要长期治疗方案，在慢性感染阶段疗效有限，并且已知会引起不良反应。对内部文库进行表型筛选，鉴定出 2,2'-亚甲基双(5-(4-溴苯基)-4,4-二甲基-2,4-二氢-3 H-吡唑-3-酮)，苯基二氢吡唑啉酮二聚体，其针对克氏锥虫的体外 pIC 50值为 5.4 。最初的优化是通过改变苯环的取代基来完成的，之后尝试替换苯环。最后，二聚体单元之间的连接体发生变化，最终形成 2,2'-亚甲基双(5-(3-溴-4-甲氧基苯基)-4,4-二甲基-2,4-二氢-3 H-吡唑- 3-one (NPD-0228) 是最有效的类似物。NPD-0228 对T. cruzi细胞内无鞭毛体的体外 pIC 50值为 6.4 ，对人 MRC-5 细胞系和小鼠心肌细胞没有明显毒性。

  frequently found in pharmaceutical compounds. To date, there is no strategy for synthesizing N-trifluoromethyl amides from abundant organic carboxylic acid derivatives, which are ideal starting materials in amide synthesis. Here, we report the synthesis of N-trifluoromethyl amides from carboxylic acid halides and esters under mild conditions via isothiocyanates in the presence of silver fluoride at room temperature

  在生物分子、药物和农用化学品中发现的含酰胺分子在自然界中无处不在，它们的衍生化代表了氟化学的重要方法学目标。三氟甲基酰胺已成为药物化合物中常见的重要官能团。迄今为止，还没有从丰富的有机羧酸衍生物合成N-三氟甲基酰胺的策略，有机羧酸衍生物是酰胺合成的理想原料。在这里，我们报告了N的合成-三氟甲基酰胺从羧酸卤化物和酯在温和条件下通过异硫氰酸酯在氟化银存在下在室温下。通过这种策略，异硫氰酸酯用 AgF 脱硫，然后将形成的衍生物酰化以提供N-三氟甲基酰胺，包括以前无法获得的结构。该方法适用范围广，凭借两个反应伙伴的多样性和可用性，为快速生成N-三氟甲基酰胺提供了平台，并应在高级中间体的改性中找到应用。
