SYNTHESIS AND SPECTRAL CHARACTERIZATION OF SOME NEW PYRAZOLINE DERIVATIVES
Abdul –Wahhab J. Al-Hamdany* and Ameera M. Farag
ABSTRACT The title compounds were synthesized by condensation azachalcones with ethylacetoacetate to get intermediate 3-(pyridyl)-5-aryl-6- ethylcarboxylate-2-cyclohexenone which were subsequently treated with hydrazine hydrate to afford the title compounds 4-(pyridyl)-6- aryl-7one-5,6-dihydro-1Hindazol or pyrazoline derivatives.[1-10] The sructures of the final products were supported by spectral data (UV, IR, 1HNMR) in addition to their physical properties. Keywords: Azachalcones, Cyclohexenones, condensation, Indazol, Pyrazoline. [Download Article] [Download Certifiate] |
