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

AbstractA green and efficient one-pot synthesis of functionalized dihydropyridines by four-component reaction of aldehydes, amine, malononitrile, and dimethylacetylenedicarboxylate in presence of meglumine has been developed. The main advantages of this new methodology are reusability of catalyst, simplicity of the starting materials, short reaction time, one-pot and high yields of products. Graphical
