AbstractSpiroimides exhibit a wide range of biological activities, such as anticonvulsant, antiarrhythmic, and antihyperglycemic activities. Herein, a novel synthetic application of renewable chemicals, itaconic acid and formamides, is described. Proper exploitation of the reactivity of itaconic acid and formamide allows for the development of an efficient synthetic approach for the production of several new biobased spiroimides, spiro[dihydroquinolin-2-one-succinimides] and spiro[indolin-2-one-glutarimides], in excellent overall yields (up to 98%).
标题:摘要
螺内酰胺具有广泛的生物活性,如抗癫痫、抗心律失常和降血糖活性。本文描述了可再生化学品丙烯二酸和甲酰胺的新型合成应用。合理利用丙烯二酸和甲酰胺的反应性,可以开发一种高效的合成方法,生产多种新的生物基螺内酰胺,如螺[二氢喹啉-2-酮琥胺]和螺[吲哚-2-酮戊二酰胺],总产率优异(高达98%)。
