, p. 1529 - 1532 (2009)
A three-component Hantzsch-type condensation of different anilines with dimedone and benzaldehyde leads to the formation of a unique acridine derivative with an unusual breaking of a C-N bond. The reaction was also carried out employing rapid microwave or

The corresponding 3,3,6,6,-tetramethyl-1,2,3,4,5,6,7,8-octahydroacridines have been obtained by the interaction of 3,3,6,6-tetramethyl-1,2,3,4,5,6,7,8,9,10-decahydroacridine-1,8-dione, its 9-Ph- and 9-p-MeOC6H4-substituted derivative

Various symmetrical and unsymmetrical decahydroacridine-1,8-dione and polyhydroquinoline derivatives were synthesized via two-step cyclocondensation reactions. The advantages of this step-wise addition of reactants in comparison with other one-pot reactions are avoiding the formation of 2 or 3 undesired by-products, therefore allowing cleaner work up of reaction. The important factor of this effective cyclocondensation method is that the prepared β-enaminone component was added dropwise to the solution, in which the Knoevenagel condensation product is slowly being formed by reaction of aldehyde molecule and 1,3-dicarbonyl compounds. The results of the proposed step-wise method are compared and discussed with those obtained in the one-pot reactions.
USY-zeolite catalyzed synthesis of 1,4-dihydropyridines under microwave irradiation: structure and recycling of the catalyst

The Hantzsch three-component reaction is the best-known multicomponent reaction, affording dihydropyridines which have been employed therapeutically and also as visible‐light photoredox catalysts. In this work we report the application of an ultra-stable
