(Z)-4-(azidomethyl)-5-chloro-2,3-dihydrobenzo[b]oxepine with terminal alkynes at room temperature in DMF afforded twenty novel (Z)-1-((5-chloro-2,3-dihydrobenzo[b]oxepin-4-yl)methyl)-1H-1,2,3-triazole derivatives in good to excellent yields. All these compounds were tested for their antibacterial properties against four strains of bacterial microorganisms including two Gram-positive and two Gram-negative species
使用铜催化的叠氮化物-炔烃环加成(CuAAC)策略首次合成了许多预先设计的苯并二氢呋喃-1,2,3-三唑杂化物。因此,在室温下,DMF中的7,9-二取代的(Z)-4-(叠氮甲基)-5-氯-2,3-二氢苯并[ b ]氧杂环丁烷与末端炔烃的快速点击反应产生了二十种新的(Z) -1-((5-氯-2,3-二氢苯并[ b ]氧杂环丁-4-基]甲基)-1 H -1,2,3-三唑衍生物的产率高至优异。测试了所有这些化合物对四种细菌微生物(包括两种革兰氏阳性菌和两种革兰氏阴性菌)的抗菌性能。其中一些对革兰氏阴性细菌表现出更好的活性(大肠杆菌(Escherichia coli)(超过革兰氏阳性菌),说明目前这类化合物对革兰氏阴性菌具有特殊功效。这些化合物还显示出对肺癌和结肠癌细胞系的细胞毒性。
