Only acridine derivative from Hantzsch-type one-pot three-component reactions
Muscia, Gisela C.,Buldain, Graciela Y.,Asis, Silvia E.
, 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
Efficient synthesis of decahydroacridine-1,8-diones and polyhydroquinolines using the step-wise method

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.
Incorporation of Keggin-based H3PW7Mo5O40into bentonite: synthesis, characterization and catalytic applications

Ag/CuO/MCM-48 as a heterogeneous catalyst was efficiently employed in the synthesis of diversely substituted symmetrical and unsymmetrical polyhydroquinoline by a multi-component reaction of arylaldehyde, dimedone, ethyl cyanoacetate and ammonium acetate. This novel method is simple, environmentally friendly, rapid, uses a recyclable catalyst and produces the products in high to excellent yields (83-97%) and lower reaction times (17-35 min). The catalyst can be reused at least 10 times without any appreciable decrease in its catalytic activities.
