Some new 1,4-disubstituted-sulfonyl-1,2,3-triazoles (3a–f, 5a–h, 7a–d, and 9a–e) were regioselectively synthesized in high yields by Cu(I) catalyzed 1,3-dipolar cycloaddition (DC) reaction of p-acetamidobenzenesulfonyl azide (p-ABSA) with terminal alkynes. These new triazole compounds were evaluated for in vitro antibacterial activity against a panel of Gram-positive Bacillus sphericus, Staphylococcus
Cu(I)催化1,3以高收率选择性合成了一些新的1,4-二取代-磺酰基-1,2,3-三唑(3a – f,5a – h,7a – d和9a – e)。顺丁烯二(DC)反应p -acetamidobenzenesulfonyl叠氮化物(p -ABSA)与末端炔烃。评估了这些新的三唑化合物对一组革兰氏阳性球菌,表皮葡萄球菌和革兰氏阴性克雷伯菌肺炎,大肠杆菌的体外抗菌活性。种类。发现这些化合物中的几种具有与商业标准青霉素-G和链霉素相当的生长抑制活性。
