与叠氮钠和端基炔“一锅法”反应合成了 10 个 1, 2, 3-三唑类磺胺化合物(Ⅲa~j)。利用 FTIR、HNMR、 CNMR
和 ESI-MS 对产物结构进行了表征。采用二倍稀释法测定了目标化合物的抗菌活性。结果表明:产物对金黄色
葡萄球菌和大肠杆菌表现出一定的抗菌活性,特别是 2-[4-(3-氟苯基)-1H-1, 2, 3-三唑-1-基]-N-(4-氨磺酰基苯基)
乙酰胺(Ⅲh)对大肠杆菌的最低抑菌浓度 MIC 为 0.25 mg/L,与阳性对照药环丙沙星相当。

Abstract: 2-Chloro-N-(4-sulfamoylphenyl)acetamide(Ⅱ) was prepared from p-amino benzene sulfonamide
with chloroacetyl chloride. Then, ten 1,2,3-triazolyl sulfonamides (Ⅲa~j) were prepared using a known
one-pot procedure starting from intermediate Ⅱ, sodium azide and terminal alkynes. The target compounds

were characterized by FTIR, HNMR, CNMR,ESI-MS and elemental analysis and their antibacterial
activities were determined by using double broth dilution method. The results showed that all the tested
compounds exhibited antibacterial activities against S.aureus and E.coli to a certain extent. In particular, the
compound 2-[4-(3-fluorophenyl)-1H-1, 2, 3-triazol-1-yl]-N-(4-sulfamoylphenyl)acetamide (Ⅲh) with a
minimal inhibitory concentration (MIC) value of 0.25 mg/L against E.coli was similar to the positive
control drug (ciprofloxacin).
Key words: sulfonamides; triazole; antibacterial activity; drug and cosmetic materials
