of the title compounds were well established on the basis of infrared (IR), 1H NMR, carbon-13 nuclear magnetic resonance (13C NMR), mass spectral data, and elemental analysis (C, H, and N). In vitro antibacterial results revealed that, the compounds 3b and 3i were found to possess an excellent broad spectrum of inhibiting potency against all the tested bacterial strains with minimum inhibitory concentration
摘要 使用一锅 Pd 从 2-碘苯甲酸和 N,N-羰基二咪唑 (CDI) 合成稠合咪唑并 [2,1-a]isoindol-5-ones (2a-d) 的有效方案已开发-催化的 C-C 键偶联。咪唑并[2,1-a]异吲哚-5-酮(2a-d)与取代的α-溴酮在甲苯中的反应以良好的产率得到相应的咪唑并[2,1-a]异吲哚鎓衍生物(3a-i)。基于红外 (IR)、1H NMR、碳 13 核磁共振 (13C NMR)、质谱数据和元素分析(C、H 和 N),标题化合物的结构已经很好地确定。体外抗菌结果表明,发现化合物3b和3i对所有受试细菌菌株具有极好的广谱抑制效力,最小抑菌浓度值为3。125 至 25 µg mL-1。图形概要
