A new, general one step synthesis of N-substituted benzisoselenazol-3(2H)-ones based on the reaction of o-iodobenzamides with lithium diselenide, is described. A series of alkyl and aryl derivatives was obtained in high yields (up to 98%). Their GPx-like antioxidant activity, tested by NMR, showed a significantly higher activity than ebselen.
描述了一种基于邻碘苯甲酰胺与二硒化锂反应的 N-取代苯并异硒唑-3(2H)-酮的新型通用一步合成方法。以高收率(高达98%)获得了一系列烷基和芳基衍生物。通过核磁共振测试,它们的类 GPx 抗氧化活性显着高于依布硒啉。
