A one-pot synthesis of novel Hantzsch dihydropyridine derivatives via a three-component cyclocondensation reaction of p-nitro acetoacetanilide, aromatic aldehyde and aqueous ammonia solution is presented. The protocol avoids the use of expensive catalyst, toxic solvent and chromatographic separation.
