Design, 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...
متن کاملDesign, synthesis, and antifungal activities of novel triazole derivatives containing the benzyl group
In previous studies undertaken by our group, a series of 1-(1H-1,2,4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-substituted-2-propanols (1a-r), which were analogs of fluconazole, was designed and synthesized by click chemistry. In the study reported here, the in vitro antifungal activities of all the target compounds were evaluated against eight human pathogenic fungi. Compounds 1a, 1q, and 1r sho...
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 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 characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
