Abstract
A Post-Ugi Brønsted acid catalyzed unprecedented fragmentation followed by in situ trapping of the alkylideneindolenine intermediate by indole nucleophiles is developed to furnish novel bis(indolyl)acetamides. The amide fragment formed during this acid catalyzed fragmentation of Ugi adduct was also isolated and characterized. The carboxylic acid and amine components of Ugi reaction were smartly chosen to allow simple water wash for removal of amide fragment to obtain the desired bis(indolyl)acetamides in pure form.
研究人员开发了一种乌基后布氏酸催化的前所未有的碎裂方法,然后通过吲哚亲核剂对亚烷基吲哚啉中间体进行原位捕获,从而生成新型的双(吲哚基)乙酰胺。在这种酸催化的 Ugi 加合物破碎过程中形成的酰胺片段也被分离出来并进行了表征。巧妙地选择了 Ugi 反应中的羧酸和胺成分,以便通过简单的水洗去除酰胺片段,从而获得所需的纯双(吲哚基)乙酰胺。
