Disodium salt 2 reacts with hydrogen peroxide to give 1,2,4-trithiolane 3, whereas treatment with methyl chloroformate yields 1,3-dithietane 4. Adding diluted NaOH to 3 leads to a mixture of an isothiazole 7 and 4. By chlorination of 2 isothiazole 8 is available. S-amination of 2 or 9 and following cyclization gives the isothiazoles 10 and 12, respectively. 3-Mercapto-acrylonitrile 14 reacts with quinones
钠盐2与过氧化氢反应生成1,2,4-三硫杂环戊烷3,而用氯甲酸甲酯处理则得到1,3-二硫杂环丁烷4。将稀的NaOH加入3中得到异噻唑7和4的混合物。通过氯化2-异噻唑8可得到。S-氨基化2或9,然后环化,分别得到异噻唑10和12。3-巯基丙烯腈14与醌反应生成缩合的草硫醇16或17。
