  Synthesis of Monocyclic Hydroperoxy- and Hydroxy-Substituted Sulfin- and Sulfonamides by Oxidation of 4,5-Dimethylisothiazolium Salts

  摘要：

  The isothiazolium salts 10, easily accessible by cyclocondensation of the thiocyanates 8 with the anilines 9, yielded with H,02 as the oxidant the first stable hydroperoxides of the 2-aryl-2,3-dihydroisothiazole 1-oxides rac-cis-13, the 1,1-dioxides 15, and their reduced 3-hydroxy derivatives rac-cis-14 and 16, respectively. The oxidation of 10 to new isothiazol-3(2H)-one 1,1-dioxides (17) is also described. For the first time, an aryl-bridged bis[isothiazolium salt] 11 was synthesized and oxidized.

  potential of these novel compounds is clearly linked to the hydroperoxide moiety. Hydroperoxides are known for their chemi- and thermochemiluminescent reactivity. In this study we tested thermochemiluminescence (TCL) as a fast method to detect and characterize the hydroperoxide moiety in structurally different synthetic organic hydroperoxides.

  氢过氧化合物对于化学工业中有机前体的选择性氧化非常重要。此外，新的3-氢过氧异噻唑1，1-二氧化物（N-邻苯二甲酰亚胺基）已被证明是有效的，乙酰胆碱酯酶（AChE）的特异性抑制剂是神经递质过程中的重要酶。这些新型化合物的抑制潜力显然与氢过氧化物部分有关。氢过氧化物因其化学和热化学发光反应性而闻名。在这项研究中，我们测试了热化学发光（TCL）作为检测和表征结构不同的合成有机氢过氧化物中氢过氧化物部分的快速方法。
