| Abstract: | 3-Cinnamoyl-4-hydroxy-6-methyl-2-pyrones (chalcone analogs of DHA) on condensation with phenylhydrazine in ethanol, yield 5-aryl-3-(4-hydroxy-6-methyl-2H-pyran-2-oxo-3-yl)-1-phenylpyrazolines which undergo smooth dehydrogenation to the corresponding pyrazoles in good yield upon treatment with iodobenzene diacetate (IBD). |
