A general, efficient, and more practical protocol for the base-mediated intermolecular or intramolecular S-arylation leading to the 2-aminobenzothiazole derivatives is reported. Remarkably, all reactions were carried out under transition-metal-free conditions with good to excellent yields, rendering the methodology presented herein highly valuable from both environmental and economic points of view
据报道,通用的,有效的和更实用的方案用于碱基介导的分子间或分子内S-芳基化反应,产生
2-氨基苯并噻唑衍
生物。值得注意的是,所有反应都是在无过渡
金属的条件下以良好至极好的收率进行的,因此从环境和经济角度来看,本文提出的方法都具有很高的价值。
