A mild and eco-friendly method has been developed for aminolysis of 3-oxirane-indolin-2-ones with aliphatic and aromatic amines to afford 3-hydroxy-3-aminomethylindolin-2-ones. An enhancement in reaction rate was observed when water was used as the reaction medium. The reactions proceed regiospecifically to open the epoxide ring from the less-substituted end.
开发了一种温和且环境友好的方法,用于与脂肪胺和芳香胺对3-环氧丙烷基吲哚啉-2-酮进行氨基分解反应,得到3-羟基-3-氨基甲基吲哚啉-2-酮。当水用作反应介质时,观察到反应速率的提高。这些反应顺利进行并特异性地从较少取代的一端打开环氧乙烷环。
