A highly regiospecific synthesis of a series of indenoindoles is reported, together with X-ray studies and their activity against human prostate cancer cells PC-3 and LNCaP in vitro. The most effective compound 7,7-dimethyl-5-[(3,4-dichlorophenyl)]-(4bRS,9bRS)-dihydroxy-4b,5,6,7,8,9bhexahydro-indeno[1,2-b]indole-9,10-dione 7q reduced the viability in both cell lines in a time and dose-dependent manner
An acid-promoted multicomponent reaction for the direct C(sp3)N bond formation was achieved through intermolecular allylic amidation in a one-pot operation to synthesize 7-acetamido tetrahydroindole derivatives from simple and readily available arylglyoxal monohydrates, acetonitriles, and enamines of 5,5-dimethyl-1,3-cyclohexadione (dimedone) has been developed. Here acetonitrile acts both as solvent

A simple, straightforward and versatile multicomponent synthetic protocol for indeno-fused heterocycles, namely diindeno[1,2-b:2′,1′-e]pyridine, indeno[1,2-b]quinoline and indeno[1,2-b]cyclopenta[e]pyridine derivatives, has been developed. The strategy involves the one pot three component reaction of enaminone, dialkyl but-2-ynedioate and 1,3-indanedione catalysed by FeCl3 in acetonitrile under reflux
Multicomponent, one-pot and expeditious synthesis of highly substituted new spiro[indolo-3,10′-indeno[1,2-b]quinolin]-2,4,11′-triones under micellar catalytic effect of CTAB in water

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。

Efficient syntheses of novel 10-aryl-5a-(arylamino)-9-hydroxy-5a,6,7,8-tetrahydroindeno[1,2-b]chromen-11(10H)-one derivatives has been reported by [4+2] cycloaddition reactions of electron-deficient 2-(arylmethylene)-1H-indene-1,3(2H)-dione heterodienes with electron-rich enaminones in [bmim]BF4 at 80 °C and in acetic acid at 80 °C. Dimedone/cyclohexane-1,3-dione enaminones have been used as dienophiles
