A simple and convenient one-pot multi-component reaction has been described for the synthesis of functionalized spirolactones. This strategy demonstrated three-component reaction between aromatic ketones (11H-indeno[1,2-b]quinoxalin-11-one) and dimethyl acetylenedicarboxylate (DMAD) in the presence of N-heterocycles, such as pyridine, quinoline, and isoquinoline in CH2Cl2 at ambient temperature without
已经描述了一种简单且方便的一锅多组分反应,用于合成功能化螺内酯。该策略证明了在存在N-杂环(例如吡啶,喹啉和异喹啉)的情况下,芳族酮(11 H-茚并[1,2 - b ]喹喔啉-11-酮)与乙酰二羧酸二甲酯(DMAD)之间发生三组分反应在室温下在CH 2 Cl 2中溶解,无需使用任何催化剂或活化剂。
