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.

We have developed green, efficient and powerful protocols for the preparation of 2,4,6-triarylpyridines and 1,8-dioxodecahydroacridines in the presence of Fe3O4@TiO2@O2PO2(CH2)2NHSO3H as a sulfonic acid-functionalized titana-coated magnetic nanoparticle catalyst under mild and solvent-free reaction conditions. These protocols furnished the desired products in short reaction times with good to high yields (20–40?min and 80–86% in the case of 2,4,6-triarylpyridines; 15–90?min and 80–93% in the case of 1,8-dioxodecahydroacridines). The final step of the mechanistic route in the synthesis of 2,4,6-triarylpyridines proceeds via an anomeric-based oxidation. Also, the nanomagnetic core–shell catalyst can be recycled and reused in both cases of the scrutinized one-pot multicomponent reactions with high turnover number and turnover frequency.
