strategy has been developed for the synthesis of structurally diverse novel 1,4-dihydropyridine frameworks bearing a 3-nitrophenyl moiety through a one-pot, four-component reaction with 4-(N,N-dimethylamino)pyridine as a catalyst at room temperature. This tandem process proceeds more effectively than previous catalytic processes.

atom-economic, one-pot protocol has been developed for the synthesis of highlyfunctionalized dihydropyridines via four-component reactions of aromatic aldehydes, arylamines, malononitrile, and dimethylacetylenedicarboxylate in the presence of sodium hydroxide in ethanol. This domino reaction proceeded smoothly in good to excellent yields and offered several advantages, including short reaction time, simple

KF/Al2O3 was found to be an efficient solid supported catalyst for the facile access of highlysubstituteddihydropyridine derivatives from the multicomponentreaction of aromatic aldehydes, amines, malononitrile, and alkylacetylenedicarboxylates. The notable advantages of this protocol are reusable catalyst, good yields, applicable to a wide range of substrates for the synthesis of pharmacologically interesting

A practical, simple and efficient method for the synthesis of polysubstituted dihydropyridines was described via multicomponent reactions of aldehydes, arylamines, dimethyl acetylenedicarboxylate and malononitrile/ ethyl acetoacetate in the presence of Fe3O4@SiO2-NH2 nanocomposites. The present methodology provides a novel and efficient method for the synthesis of dihydropyridine derivatives with some advantages, such as excellent yields, short reaction times, recoverability and low catalyst loading. The nanomagnetic catalyst could be readily recovered using an external magnet and reused several times without any significant loss in activity. The catalyst was fully characterized by FT-IR, SEM, XRD, EDX and VSM analysis.
