, p. 1346 - 1351 (2018/04/14)
A simple and efficient one-pot synthesis of tetrahydroacenaphtho[1,2-b]indolone derivatives via four-component reaction of 5,5-dimethylcyclohexane-1,3-dione (dimedone), arylamines, acenaphthoquinone, and active methylene compounds under catalyst-free conditions is described. The reactions were carried out under mild conditions using ethanol as solvent. Advantages of this method include simple experimental and workup procedure, readily available starting materials, and high yields.

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.

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
An improved method for the synthesis of carbazolones by palladium/copper-catalyzed intramolecular annulation of n -arylenaminones
Weng, Bojie,Liu, Rui,Li, Jing-Hua
experimental part, p. 2926 - 2930 (2010/10/18)
An improved method for the synthesis of carbazolones via the condensation of arylamines with 1,3-cyclodiketones followed by intramolecular oxidative cyclization catalyzed by palladium acetate and copper acetate in ethanol under an oxygen atmosphere was established. The improved method has the advantage of easily available starting materials and affords good yields.
