چکیده

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)oxy)pyrimidine showed bleaching activity to green weeds. In greenhouse conditions, this compound also showed excellent post-emergence herbicidal effect against Digitaria sanguinalis L. at the dosage of 750 g a. i. ha(-1).

Synthesis and herbicidal activity of substituted pyrazole isothiocyanates.

Isothiocyanates and substituted pyrazoles were combined to form a series of novel isothiocyanates with highly effective herbicidal activity. The target compounds were analyzed by elemental analysis, 1H-NMR, EI-MS and IR spectroscopy. The synthesized compounds, particularly compounds 3-1 and 3-7, exhibited good herbicidal activities against four weeds. The EC(50) values of compound 3-1 against E...

N-methyl pyridinium-p-toluene Sulfonate (NMPyTs) catalyzed synthesis of pyrano[2,3-c]pyrazoles

Abstarct:A simple one-pot synthesis of pyrano[ 2,3-c]pyrazoles was developed by a three-component reaction of various benzaldehydes, malononitrile and 1-phenyl or hydro-3-methyl-1H-pyrazol-5(4H)-one in the presence of N-methyl pyridinium p-toluene sulfonate (NMPyTs) as a catalyst. All of the synthesized compounds were identified by IR, 1H NMR, 13C NMR and mass spectroscopy techniques. In the me...

Efficient synthesis of 1,3-diaryl-4-halo-1H-pyrazoles from 3-arylsydnones and 2-aryl-1,1-dihalo-1-alkenes

An efficient synthesis of 1,3-diaryl-4-halo-1H-pyrazoles was achieved. The synthesis involves the [3 + 2] dipolar cycloaddition of 3-arylsydnones and 2-aryl-1,1-dihalo-1-alkenes. The process proceeds smoothly in moderate to excellent yields. 1,3-Diaryl-4-halo-1H-pyrazoles are found to be important intermediates that can easily be converted into 1,2,5-triaryl-substituted pyrazoles via Pd-catalyz...

Synthesis and study of antibacterial activity of some 1-phenyl-3-aryl-5-(4-(2-ethanoloxy) phenyl)-1H-pyrazoles

A series of 1-phenyl-3-aryl-5-(4-(2-ethanoloxy) 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 yielded the corresponding 1-phenyl-3-aryl-5-(4-hydroxyphenyl)-1H-pyrazoles 2 which on further reaction with 3-chloroethanol furnished the title co...
