A synthesis of 3-substituted benzisothiazoles starting from readily available o-mercaptoacylphenones is presented. The key cyclization step features a mild S-nitrosation and its succeeding intramolecular aza-Wittig reaction leading to the construction of the title compounds.
提出了从容易获得的邻巯基酰基苯甲酮开始的3-取代的苯并异噻唑的合成。关键的环化步骤具有温和的S-亚硝化作用及其随后的分子内aza-Wittig反应,从而导致标题化合物的构建。
