A simple, straightforward and versatile multicomponent protocol for the synthesis of indanone-fused spirooxindole derivatives has been developed. The strategy involves the one-pot three-component reaction of heterocyclic ketene aminals, 1H-indene-1,3(2H)-dione and the dicarbonyl compounds isatins or acenaphthenequinone in an ethanol/water medium catalysed by p-TSA at reflux. Mild reaction conditions
已经开发了一种用于合成茚满酮稠合螺吲哚衍生物的简单、直接和通用的多组分方案。该策略涉及杂环烯酮胺醛、1H-茚-1,3(2H)-二酮和二羰基化合物靛红或苊醌在乙醇/水介质中的一锅三组分反应,该反应由 p-TSA 在回流下催化。温和的反应条件、操作简单、底物范围广和整体优异的收率使该方法非常有效地用于茚满酮稠合螺吲哚的文库合成。
