phenyl)-l,3,4-oxadiazolin-5-thiones 5a-e. The structure of the newly synthesized compounds have been established by analytical and spectral data. These compounds have also been screened for their biological activity.
4-(氯磺酰基)苯甲酸与二乙胺缩合得到4(二乙基氨磺酰基)苯甲酸1,将其酯化得到甲酯2。化合物2与水合肼缩合得到肼衍生物3。该中间体与二硫化碳发生环化和氢氧化钾以产生取代的 1,3,4-恶二唑啉-5-硫酮 4. 使用不同的胺对 4 进行氨基甲基化,提供 4-取代的氨基甲基-2-(4'二乙基磺酰胺苯基)-1,3,4-恶二唑啉-5-硫酮 5a -e. 新合成化合物的结构已通过分析和光谱数据确定。还对这些化合物的生物活性进行了筛选。
