oxychloride and with phenacyl bromides afforded two series of fused heterocycles namely; 6-substituted-3-2-(aryloxymethyl)phenyl}-1,2,4- triazolo[3,4-b][1,3,4]thiadizoles (6a-t) and 6-substituted-3-2-(aryloxymethyl)phenyl)}[1,2,4]triazolo[3,4-b][1,3,4] thiadiazines (7a-p) respectively. The structures of these newly synthesized compounds were established on the basis of their IR, 1H-NMR 13C-NMR and Mass
2-(芳氧基甲基)苯甲酸酰肼与二硫化碳在氢氧化钾存在下反应,然后水合肼反应,得到4-氨基-3 2-(芳氧基甲基)苯基} [1,2,4]三唑-5-硫醇(5a-d)。在氯氧化磷和苯甲酰溴的存在下,5a-d与各种芳族羧酸的环缩合得到两个系列的稠合杂环:6-取代的-3- 2-(芳氧基甲基)苯基} -1,1,2,4-三唑[3,4-b] [1,3,4]噻二唑(6a-t)和6-取代的-3- 2-(芳氧基甲基)苯基)} [1,2,4]三唑并[3,4-b] [1,3,4]噻二嗪(7a-p)。这些新合成的化合物的结构是根据其IR,1H-NMR,13C-NMR和质谱数据确定的。筛选所有标题化合物的抗微生物和抗炎活性。
