Synthesis, Identification, and Evaluation of Antibacterial Activity of Some New 4,5-Dihydro-1H-Pyrazoles, Derivatives from Substituted Chalcones
In this work, a series of new 4,5-dihydro-1H-pyrazole derivatives (M21-M25) has been synthesized successfully via the reaction of different aldehydes with ketones to produce chalcones, followed by the reaction with hydrazine and phenyl hydrazine. The prepared compounds were identified using FT-IR spectroscopy, 1H NMR spectroscopy, and 13C NMR spectroscopy.
