we report the design and eco‐benign synthesis of new class of carbazolyl‐1,4‐dihydropyridine (1,4‐CDHP) and carbazolyl‐1,8‐dioxodecahydroacridine (CAD) derivatives via a three‐component coupling reaction of substituted carbazole aldehydes, ethyl acetoacetate/dimedone, and ammonium acetate under solvent‐free conditions at 112°C to 115°C. We also report an efficient one‐pot synthesis of new class of
在本研究中,我们报告了通过三组分偶联作用设计的新型咔唑基-1,4-二氢吡啶(1,4-CDHP)和咔唑基-1,8-二氧十二烷基氢化hydro啶(CAD)衍生物的设计和生态友好合成取代咔唑醛,乙酰乙酸乙酯/二甲酮和乙酸铵在无溶剂条件下于112°C至115°C下反应。我们还报告了在乙腈/水介质(3:1)下,通过取代的乙酰乙酸乙酯,二甲酮,乙酸铵和咔唑醛的四组分偶联反应,可以有效地一锅合成新型咔唑基聚氢喹啉(CPQ)衍生物。 73°C至75°C,中等产量。所有的产品进行了彻底的特征在于1 H NMR,1313 C NMR,傅立叶变换红外(FTIR),质谱和CHN分析。评估了合成的杂环化合物对革兰氏阴性和革兰氏阳性细菌致病菌株的体外抗菌活性。活性化合物的最小抑菌浓度(MIC)通过宏观稀释法进行评估。CPQ衍生物(8a)对大肠杆菌,铜绿假单胞菌和伤寒沙门氏菌表现出优异的抗菌活性。与参考药物相比的MIC值为16
