Some 3-(Substituted methylthio)-4-phenyl-5-(3,4,5-trimethoxyphenyl)-4H-1,2,4-triazole derivatives were synthesized in six steps starting from easily accessible gallic acid. The resulting sulfides were then catalytically oxidized to the title sulfones with H2O2. The products were obtained in high yield under mild conditions and practically devoid of any by-products. The structures were confirmed by
一些 3-(取代的甲硫基)-4-苯基-5-(3,4,5-三甲氧基苯基)-4H-1,2,4-三唑衍生物是从容易获得的没食子酸开始的六个步骤中合成的。然后用 H2O2 将所得硫化物催化氧化为标题砜。在温和的条件下以高产率获得产物,并且几乎没有任何副产物。通过元素分析、IR、1H-和13C-NMR光谱数据证实了结构。此外,还对模型三唑 7g 进行了详细的 X 射线晶体学结构分析。
