A series of some new 1-thiocarbamoyl-3-(2,5-dimethylfuran-3-yl)-5-(fluoro/trifluoromethylphenyl) -2-pyrazolines 4a-f have been synthesized by treating with various fluoro/trifluoromethyl substituted chalcones, thiosemicarbazide and potassium carbonate using conventional heating and solventfree microwave irradiation techniques. The easy work-up of the products, rapid reaction and mild conditions are noticeable features of this protocol. Synthesized compounds have been screened for their in vitro antimicrobial activity against six microbial strains. Among them, 1-Thiocarbamoyl-3-(2,5-dimethylfuran-3-yl)-5-(3-fluorophenyl)-2-pyrazoline 4b showed maximum zone of inhibition against all the tested microorganisms. Structural elucidation of the synthesized compounds were determined on the basis of various spectroscopic methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
