The synthesis of some condensed indolizinediones derived from pyroglutamic acid is described. Treatment of these ketones in HCl, HBr or MeONa/MeOH furnished aryl propionic acid derivatives. During the ketone transformations, two sequential processes could take place in competitive manner to provide heterocyclic systems bearing carboxylic acid or hydroxycarboxylic acid function. Easy synthesis of amides
描述了一些衍生自焦谷氨酸的缩合吲哚并二酮的合成。在HCl,HBr或MeONa / MeOH中处理这些酮,得到芳基丙酸衍生物。在酮转化过程中,可以以竞争的方式进行两个连续的过程,以提供具有羧酸或羟基羧酸功能的杂环体系。酰胺的容易合成表明,可以从这些系列中获得融合在γ-咔啉和异喹啉核上的潜在DNA插入杂环系统。
