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. Inhibitory effects were also observed on the adhesion, migration, and invasion of the prostate cancer cells as well as on clonogenic possibly by inhibition of MMP-9 activity. Molecular docking of 7q and 6k into MMP-9 human active site was also performed to determine the probable binding mode.

An efficient, inexpensive, environmentally friendly and high yield one-pot route to 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. This method works on a large scale in excellent yields.

Datta, Bandita,Pasha
experimental part, p. 171 - 177 (2011/04/22)
Silica sulfuric acid, a heterogeneous reagent, has been found to be an efficient catalyst for the synthesis of β-enaminones and β-enaminoesters under microwave irradiation in a microwave reactor within 2 min. The experimental procedure is simple and environment-friendly, and results in excellent yields of the products. Further, the catalyst is recyclable, and the reaction is 60 times faster than the reaction at room temperature. Copyright Taylor & Francis Group, LLC.
Molecular iodine-catalyzed mild and effective synthesis of β-enaminones at room temperature
Datta, Bandita,Reddy, M. B. Madhusudana,Pasha
experimental part, p. 2331 - 2336 (2011/06/27)
Molecular iodine has been found to be an efficient and ecofriendly catalyst for the synthesis of β-enaminones from dimedone and amines at room temperature in the presence of acetonitrile within 60 min. The experimental procedure is simple, includes shorter reaction times, and results in excellent yields of the products. Copyright
NaHSO4/SiO2: An efficient catalyst for the synthesis of β-enaminones and 2-methylquinolin-4(1H)-ones under solvent-free condition
Sapkal, Suryakant B.,Shelke, Kiran F.,Shingate, Bapurao B.,Shingare, Murlidhar S.
experimental part, p. 723 - 726 (2011/03/19)
An efficient and simplified protocol for NaHSO4/SiO2 catalyzed solvent-free synthesis of β-enaminone and 2-methylquinolin-4(1H)- one derivatives under microwave irradiation is described. A series of functionalized derivatives have been synthesized in shorter reaction times with moderate to good yields. The use of milder catalyst in non-conventional method offers significant advantages over conventional methods, such as higher selectivities, simplicity, solvent-free reaction and non-environmental polluting conditions.
