titled compounds using thionyl chloride (SOCl2) in catalytic amount. The synthesized compounds were confirmed for their structure by means of various spectrometric techniques like IR, 1H NMR, 13C NMR, Mass spectra, and Elemental analysis. Thus-obtained chalcone derivatives were tested for their antibacterial and antifungal activities and were reported in form of minimum inhibitory concentration values
作者通过酸催化的醛醇缩合反应合成了具有查耳酮的苯并咪唑衍生物作为主要基序。所需化合物的合成通过进行两个平行反应而开始:(i)2-巯基苯并咪唑的合成和(ii)由4-氨基苯乙酮合成N-(4-乙酰基苯基)-2-氯乙酰胺。使用丙酮作为溶剂,并用K 2 CO 3作为清除剂,将如此制备的两种中间体缩合,得到2-(1H-苯并[d]咪唑-2-基硫基)-N-(4-乙酰苯基)乙酰胺(II)。使用亚硫酰氯(SOCl 2)使所得产物与不同取代的醛进一步反应,生成标题化合物)的催化量。通过各种光谱技术,例如IR,1 H NMR,13 C NMR,质谱和元素分析,确认合成的化合物的结构。测试由此获得的查耳酮衍生物的抗菌和抗真菌活性,并以最小抑制浓度值的形式报告。
