3-triyl)]tetrakis(6,8-diaryl[1,2,4]triazolo[3,4-b][1,3,4]thiadiazepines), were synthesized starting from dimethyl 4-hydroxyisophthalate which was reacted with dibromomethane to obtain tetramethyl 5,5′-[methylenebis(oxy)]di(benzene-1,3-dicarboxylate). The latter was treated with excess hydrazine hydrate, and the resulting tetrahydrazide was converted to tetrakis-1,2,4-triazolyl derivative via cyclization with
标题化合物,3,3',3",3'''-[亚甲基双(氧基苯-5,1,3-三基)]四(6,8-二芳基[1,2,4]三唑并[3,4] -b][1,3,4]thiadiazepines),由 4-羟基间苯二甲酸二甲酯与二溴甲烷反应得到 5,5'-[亚甲基双(氧基)]二(苯-1,3-二羧酸)四甲酯合成. 后者用过量的水合肼处理,所得四酰肼通过与乙醇氢氧化钾、二硫化碳和水合肼的环化作用转化为四-1,2,4-三唑基衍生物。在最后阶段,与取代的查耳酮环缩合得到目标产物。通过元素分析和 FT-IR 和 NMR 光谱证实了新合成化合物的结构,
