Synthesis and fungicidal activity of pyrazole derivatives containing 1,2,3,4-tetrahydroquinoline
BACKGROUND Take-all of wheat, caused by the soil-borne fungus Gaeumannomyces graminis var. tritici, is one of the most important and widespread root diseases. Given that take-all is still hard to control, it is necessary to develop new effective agrochemicals. Pyrazole derivatives have been often reported for their favorable bioactivities. In order to discover compounds with high fungicidal act...
متن کاملSynthesis and Antioxidant Activity of 2-Amino-5-methylthiazol Derivatives Containing 1,3,4-Oxadiazole-2-thiol Moiety
A series of new 5-(2-amino-5-methylthiazol-4-yl)-1,3,4-oxadiazole-2-thiol derivatives 6(a-j) were designed and synthesized with various substituted aldehydes. The chemical structures were confirmed by elemental analyses, FT-IR, (1)H NMR, and mass spectral studies. The antioxidant activity of the synthesized compounds was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl, nitric oxide,...
متن کاملNew Schiff bases derivatives containing anthracene moiety: Synthesis and fungicidal activity
New 5-[1-(anthracen-9(10H)-ylideneamino)-2-(1H-imidazol-5-yl)ethyl]-1,3,4-thiadiazol-2-amine 3 has been synthesized from condensation reaction of N-anthracen-9(10H)-ylidenehistidine 2 with thiosemicarbazide in phosphorusoxy chloride. The prepared compounds were characterized by FTIR spectroscopy, electronic spectroscopy, NMR and NMR. Preliminary in vitro tests for fungicidal activity show that ...
متن کاملSynthesis and systemic fungicidal activity of silicon-containing azole derivatives.
A new series of azole derivatives containing silicon were synthesized and evaluated for fungicidal activity against rice sheath blight by submerged application. Among them, 2-(4-fluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-trimethylsilylpr opan-2-ol (9a) exhibited satisfactory efficacy at 12.5 grams per 10 ares.
متن کاملDesign, synthesis and fungicidal activities of some novel pyrazole derivatives.
In order to discover new compounds with good fungicidal activities, 32 pyrazole derivatives were designed and synthesized. The structures of the target compounds were confirmed by 1H-NMR, 13C-NMR, and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), and their fungicidal activities against Botrytis cinerea, Rhizoctonia solani Kuhn, Valsa mali Miyabe et Yamada, Thanatephorus...
