ebselen analogs, having Se⋯O(ester) secondary bonding interaction, is described. The reaction of dimethyl 2-(bromoselanyl)-5-tert-butylisophthalate (4) with different diprotic amines such as ethanolamine, 2-chloroethylamine, and N,N′-dimethylethylenediamine afforded the ebselen analogs. Reaction of 4 with ethylenediamine and tris(2-aminoethyl)amine resulted in the formation of bis- and tris-ebselen derivatives
描述了一种具有Se⋯O(酯)二级键相互作用的依布硒啉类似物的简便合成方法。2-(溴代布兰基)-5-叔丁基间苯二甲酸二甲酯(4)与不同的二质子胺如乙醇胺,2-氯乙胺和N,N'-二甲基乙二胺的反应提供了ebselen类似物。的反应4与乙二胺和三(2-氨基乙基)胺分别导致双-和三依布硒啉衍生物的形成,。
