efficient method for preparing benzothiazolone derivatives was developed by a domino coupling reaction between the disulfide and COS in the present of NaOH. Notably, the C=O of COS was converted into benzothiazolone by carbonylation reaction and the sulfur of COS was transformed into sulfur and sulfide after cleaving the S–S bond under mild conditions. This efficient synthetic methodology could provide
通过在NaOH存在下二硫键与COS之间的多米诺骨牌反应,开发了一种制备苯并噻唑酮衍生物的有效方法。值得注意的是,通过羰基化反应,COS的C = O转化为苯并噻唑酮,在温和条件下裂解S-S键后,COS的硫转化为硫和硫化物。这种有效的合成方法可以为利用COS提供有希望的过程。
