The synthesis of 4,7-di- and 4,7,7-trisubstituted 3,6-dioxoperhydropyrrolo[1,2-a]pyrazine-7-carboxylale derivatives is described. The approach used for the preparation of this heterocyclic template is based on the reductive animation of 4-ketodiesters derived from dipeptides.
描述了4,7-二-和4,7,7-三取代的3,6-二氧杂氢吡咯并[1,2 - a ]吡嗪-7-羧基衍生物的合成。用于制备该杂环模板的方法基于衍生自二肽的4-酮二酯的还原动画。
