Synthesis and Antimicrobial Activity of Some New 2-Pyrazoline Derivatives

B. Ramesh, S. Babitha and Y. Rajendra Prasad

Some new pyrazoline derivatives were synthesized by reacting chalcones of 2-acetyl thiophene with phenyl hydrazine hydrochloride in the presence of alcohol. The synthesized compounds were identified by spectral data and screened for antimicrobial activity. Some of these compounds showed moderate to considerable antimicrobial activity.
