A three-component procedure for the preparation of 2-substituted benzothiazoles from nitroarenes, alcohols, and sulfur powder is described. The reaction showed a good functional group tolerance to provide the heterocyclic products in moderate to good yields. The sequential assembly involving nitro reduction, C–N condensation, and C–S bond formation has been realized in one pot.
描述了一种由硝基芳烃,醇和硫粉制备2-取代的苯并噻唑的三组分方法。该反应显示出良好的官能团耐受性,以中等至良好的产率提供了杂环产物。在一个罐中就实现了包括硝基还原,C–N缩合和C–S键形成的顺序组装。
