Synthesis and Herbicidal Activity of 5-Heterocycloxy-3-methyl-1-substituted-1H-pyrazoles.
With the objective of finding valuable herbicidal candidates, a series of new 5-heterocycloxy-3-methyl-1-substituted-1H-pyrazoles were synthesized and their herbicidal activities were evaluated. The bioassay results showed that some compounds exhibited excellent herbicidal activities at the concentration of 100 mg/L, and compound 5-chloro-2-((3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazol-5-yl)ox...

3-(2’-n-butylbenzofuran-3’-yl)-5-aryl-4, 5-dihydro-1H-pyrazoles (4a-4k) have been synthesized. The synthesized products have been assayed for their antimicrobial activity against Gram+ve, Gram-ve bacteria and fungi. All the synthesized products were assigned with IR, 1HNMR, Mass Spectra, TLC, and elemental analysis. Some of the products showed moderate activi...

متن کاملNITROIMIDAZOLES XI1 [I]: SYNTHESES OF TRISUBSTITUTED PYRAZOLES AND SUBSTITUTED (1 -METHYL-5-NITRO-2- IMIDAZOLYL) PYRIMIDINONES
The reaction of P-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1- methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5- nitro-2-imidazoly1) -1-phenylpyrazole (3). The reaction of diketones (1) with urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl- 5-nitro-2-imidazolyl)-1-(lH)pyrimidones (4). The structures of all compounds w...
متن کاملSynthesis and Antibacterial Activity of Some 1-Phenyl-3-aryl-5-(4-(3-propanoloxy) phenyl)-1H-pyrazoles
A series of 1-phenyl-3-aryl-5-(4-(3-propanoloxy) phenyl)-1H-pyrazoles were synthesized from chalcones and studied for their in vitro antibacterial activity. Chalcones i.e.,1-aryl-3-(4hydroxyphenyl) prop-2-en-1-ones (1) on reaction with phenyl hydrazine in presence of acetic acid and few drops of HCl yielded the corresponding 1-phenyl-3-aryl-5-(4-hydroxyphenyl)-1H-pyrazoles (2) which on further ...
