6-Iodo-substituted carboxy-quinolines were obtained using a one-pot, three-component method with trifluoroacetic acid as a catalyst under acidic conditions. Iodo-aniline, pyruvic acid and 22 phenyl-substituted aldehydes (we varied the type and number of radicals) or O-heterocycles, resulting in different electronic effects, were the starting components. This approach offers advantages such as rapid
以三氟乙酸为催化剂,在酸性条件下,采用一锅三组分法得到6-碘代羧基喹啉。碘苯胺、丙酮酸和 22 个苯基取代的醛(我们改变了自由基的类型和数量)或 O-杂环,产生不同的电子效应,是起始成分。这种方法具有快速响应时间、经济高效的催化剂、高产品收率和高效纯化程序等优点。进行了全面的研究以检查醛结构对合成途径的影响。获得了化合物库,并通过 FT-IR、MS、1H NMR 和 13C NMR 光谱以及单射线晶体衍射法进行了表征。体外测试了它们对表皮葡萄球菌、肺炎克雷伯菌和近平滑念珠菌的抗菌活性。还研究了碘喹啉衍生物对微生物粘附(微生物生物膜发育的初始阶段)的影响。这项研究表明,带有碘原子的羧基喹啉衍生物是开发新型抗菌剂的有趣支架。
