3-hydroperoxy-, 3-hydroxy- and 3-oxoisothiazole 1,1-dioxides have been synthesized by the sequence of oxidation reactions from N,N′-linked isothiazolium perchlorates with hydrogen peroxide, MMPP, and pyridinium dichromate. Isothiazolium salts without acceptor substituents did not give N-substituted sultams. Novel N,N′-bisazaheterocycles were investigated as inhibitors of acetylcholinesterase (AChE) and human leukocyte
N-邻苯二甲酰亚胺基和 N-喹唑啉基取代的 3-氢过氧、3-羟基和 3-氧代异噻唑 1,1-二氧化物已通过 N,N'-连接的高氯酸异噻唑鎓与过氧化氢的一系列氧化反应合成, MMPP和重铬酸吡啶鎓。没有受体取代基的异噻唑盐不产生N-取代的磺胺嘧啶。研究了新型 N,N'-双氮杂杂环化合物作为乙酰胆碱酯酶 (AChE) 和人白细胞弹性蛋白酶 (HLE) 的抑制剂。发现两种 2,3-dihydro-3-hydroperoxy-2-(phthalimid-1-yl)isothiazole 1,1-dioxides 可抑制 AChE。
