new spiro[indolo-3,10′-indeno [1,2-b]quinolin]-trione derivatives has been developed, involving three-component reaction of enaminones, N-substituted isatins and Indane-1,3-dione catalyzed by FeCl3. The approach to this spiro-heterocycle is noteworthy because it results in the formation of three new σ (two C–C and one C–N) bonds in a single operation, leading to the construction of novel spiro skeleton
已开发出一种高效,廉价,环保且高收率的锅法合成新的螺[indolo-3,10'-茚并[1,2- b ]喹啉]-三酮衍生物,涉及烯胺酮的三组分反应, FeCl 3催化N-取代的isatins和Indane-1,3-dione 。值得注意的是,这种螺旋杂环的方法会导致在一次操作中形成三个新的σ键(两个C–C和一个C–N),从而构造出新颖的螺旋骨架。该方法以优异的产量大规模工作。

aminopyrazoles, aminoisoxazole, aminoisothiazole, amino uracils, and aliphatic enamines has been developed in an aqueous medium using hydrogenperoxide as a benign oxidant and ammonium thiocyanate as a thiocyanating agent. On the otherhand, the reaction of hydrogenperoxide and ammonium thiocyanate followed by one-pot addition of NaOH provides the corresponding disulfides in the case of amino azoles, and

A convenient multicomponent reaction strategy for the synthesis of highly substitutednew 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。
