Abstract

Synthetic pyrazole derivatives (5a-f) have been synthesized using conventional method producing good yield in ethanol with hydrazine in presence of acid. The oxidative cyclization reaction of chalcones (3a-f), with iodine crystals in presence of DMSO gives good yield of chromone (4a-f) derivatives these synthesized compounds were confirmed by IR, 1H NMR and mass spectral data.
