A convenient multicomponent reaction strategy for the synthesis of highly substituted new spiro[indolo-3,10′-indeno[1,2-b]quinolin]-2,4,11′-triones has been developed under CTAB/H2O system (easily recovered and recycled) to provide spiro products with excellent yields. The most exciting feature of this methodology is its mechanism involving the unusual ring opening of an isatin moiety followed by recyclisation
在CTAB / H 2 O体系下,开发了一种方便的多组分反应策略,用于合成高度取代的新螺[indolo-3,10'-茚并[1,2- b ]喹啉] -2,4,11'-三酮。(易于回收和再循环),以提供高产量的螺环产品。该方法学最令人兴奋的特征是其机制涉及伊斯兰素部分的异常开环,然后进行环化。
