Synthesis of new generation of 1, 4-dihydropyridines

A multicomponent reaction for the synthesis of new generation of dihydropyridines from pyrazole carbaldehyde, dimedone and ammonium nano-Fe(3)O(4) as an effective and reusable catalyst is reported. The present methodology offers several advantages, such as a simple procedure with an easy work-up, short reaction times, high yields, and the absence of any volatile and hazardous organic solvents
