3-c][1,2,4]triazoles for which two main synthetic approaches exist. Here we report a new synthetic protocol that allows the preparation of these tricyclic compounds via the oxidation of a mercaptophenyl moiety to its corresponding disulfide. Subsequent C-H bond functionalization is thought to enable an intramolecular ring closure, thus forming the desired benzo[4,5]thiazolo[2,3-c][1,2,4]triazole. This
许多含氮和硫的杂环化合物表现出生物活性。这些杂环化合物包括苯并[4,5]噻唑并[2,3-c][1,2,4]三唑,存在两种主要的合成方法。在这里,我们报告了一种新的合成方案,该方案允许通过将巯基苯基部分氧化为其相应的二硫化物来制备这些三环化合物。随后的 CH 键官能化被认为能够实现分子内闭环,从而形成所需的苯并[4,5]噻唑并[2,3-c][1,2,4]三唑。该方法结合了高官能团耐受性、短反应时间和良好至优异的产率。
