potassium hydroxide followed by hydrazine hydrate gave 4-amino-5-[4-(methylsulfonyl)benzyl]-4H-[1,2,4]triazole-3-thione (4). The resulting triazole was subjected to cyclocondensation reaction with different phenacyl bromides to afford 6-substituted-3-[4-(methylsulfonyl)benzyl]-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines (5a–i). All structures of the newly synthesized compounds were confirmed by IR, NMR, mass
4-(甲基磺酰基)苯基乙酰肼(3)与二硫化碳和氢氧化钾的反应,然后与水合肼反应,得到4-氨基-5- [4-(甲基磺酰基)苄基] -4 H- [1,2,4]三唑- 3-硫酮(4)。将得到的三唑进行缩合反应与不同的苯甲酰甲基溴化物,得到6-取代的3- [4-(甲磺酰基)苄基] -7- ħ - [1,2,4]三唑并[3,4- b ] [1, 3,4]噻二嗪(5a – i)。通过IR,NMR,质谱研究和元素分析证实了新合成化合物的所有结构。筛选新合成的化合物的细胞毒性,抗菌和抗真菌活性。一些衍生物表现出有希望的生物学活性。
