Abstract

An efficient, three component synthesis of novel class of mono, bis and trisdihydropyridines which are fused with pyrazole rings from reaction between pyrazolecarbaldehyde, dimedone and ammonium acetate was described. In this research, mono, bis and trisdihydropyridines were synthesized in the presence of a catalytic amount of recyclable catalyst, nano particle Fe3O4.

Keywords: Dihydropyridines, dimedone, nano Fe3O4, pyrazole.
