The synthesis of some 3‐(4‐aryl‐benzofuro[3,2‐b]pyridin‐2‐yl)coumarins 3a–r has been carried out by the reaction of 3‐coumarinoyl methyl pyridinium salts 1a–c with 2‐arylidene aurones 2a–f in the presence of ammonium acetate and acetic acid under Kröhnke's reaction conditions. All the synthesized compounds were characterized by analytical and spectral data. They have been screened for their antibacterial
某些3-(4-芳基-苯并呋喃[3,2- b ]吡啶-2-基)香豆素3a-r的合成是通过3-香豆素酰基甲基吡啶鎓盐1a-c与2-亚芳基的反应进行的噢哢2A-F在乙酸铵和乙酸的Kröhnke的反应条件下的存在。所有合成的化合物均通过分析和光谱数据表征。筛选了它们作为革兰氏阴性菌对大肠杆菌(ATCC 25922)的抗菌活性,作为革兰氏阳性菌对枯草芽孢杆菌(ATCC 1633)的研究以及对黑曲霉(ATCC 9029)的抑菌活性。
