Abstract
A series containing sixteen titled pyrazoline derivatives have been synthesized by perchloric acid catalyzed cyclization cum acetylation of 3-hydroxyphenyl chalcones, hydrazine hydrate and acetic anhydride by refluxing condition. The yields of the synthesized N-acetylpyrazolines were found to be more than 90%. These 1-acetylpyrazolines were characterized by their physical constants and spectral data. The antioxidant activities of these pyrazolines derivatives have been evaluated by 2,2- diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity.
