A series of new 4-(3,4dimethoxyphenethyl)-3,5-akyl/aryl-4H- 1,2,4-triazoles (3a-g) were obtained by reaction of ethyl N'-(alkylidene/arylidene)hydrazonate (1) and 2-(3,4-dimethoxy phenyl)ethanamine (2). Compounds 4d, e, and g were synthesized from the reaction of corresponding compounds 3d, e, and g with BBr_3, respectively. The 10 new compounds synthesized were characterized by elemental analyses, IR, ^1H-NMR, and ^13}C-NMR spectral data. The structure of compound 3g was inferred through IR, ^1H-, ^13}C-NMR, elemental analyses, and X-ray spectral techniques. In addition, the newly synthesized chemicals were screened for their antioxidant properties. Among the chemicals tested, 4d, e, and g exhibited the highest degree of antioxidant activity.
通过乙基N'-(烷基/芳基)腙(1)和2-(3,4-二甲氧基苯基)乙胺(2)的反应,获得了一系列新的4-(3,4二甲氧基苯乙基)-3,5-烷基/芳基-4H-1,2,4-三唑(3a-g)。化合物4d、e和g分别由相应的化合物3d、e和g与BBr_3的反应合成。通过元素分析、红外光谱、^1H-核磁共振和^13}C-核磁共振光谱数据,对合成的10种新化合物进行了表征。通过红外光谱、^1H-、^13}C-核磁共振、元素分析和X射线光谱技术推断出化合物3g的结构。此外,还对新合成的化学物质进行了抗氧化性能筛选。在测试的化学物质中,4d、e和g表现出最高的抗氧化活性。
