Synthesis and fungicidal activity of novel 2,3-disubstituted-1,3-benzoxazines.
A series of new 2,3-disubstituted-3,4-dihydro-2H-1,3-benzoxazines were prepared in moderate to excellent yields by aza-acetalizations of aromatic aldehydes with 2-(N-substituted aminomethyl)phenols in the presence of TMSCl. Their structures were confirmed by IR, ¹H-NMR, ¹³C-NMR, MS and elemental analysis. The fungicidal activities of the target compounds were preliminarily evaluated, and some c...
متن کاملSynthesis and fungicidal activity of novel 2,5-disubstituted-1,3,4-oxadiazole derivatives.
A novel series of 1,3,4-oxadiazole derivatives containing a 5-phenyl-2-furan moiety were synthesized from the intermediates diacylhydrazine 3 and acylhydrazone 5 via an efficient approach under microwave irradiation in good yields. Their structures were characterized by IR, (1)H NMR, and elemental analysis. The antifungal tests indicated that the title compounds showed in vivo fungicidal activi...
متن کاملSynthesis and fungicidal activity of novel 2,5-disubstituted-1,3,4- thiadiazole derivatives containing 5-phenyl-2-furan
A series of 2,5-disubstituted-1,3,4-thiadiazoles were synthesized using Lawesson's reagent by an efficient approach under microwave irradiation in good yields. Their structures were characterized by MS, IR, (1)H NMR, (13)C NMR, and elemental analysis. Their in vitro and in vivo fungicidal activities revealed that the title compounds exhibited considerable activity against five selected fungi, e...
متن کاملSynthesis and Fungicidal Activity of 1-(Carbamoylmethyl)-2-aryl-3,1-benzoxazines.
A series of new 1-(carbamoylmethyl)-2-aryl-3,1-benzoxazines were prepared in moderate to good yields by BF₃·OEt₂-catalyzed reactions of aromatic aldehydes with 2-(N-substituted carbamoylmethylamino)benzyl alcohols. The structures of the target compounds were confirmed by IR, ¹H-NMR, 13C-NMR, and elemental analyses. The fungicidal activities of the target compounds against plant fungi were preli...
متن کاملDesign, Synthesis and Biological Activity of 4,6-disubstituted Pyridin-2(1H)-ones as Novel Inhibitors of Soluble Epoxide Hydrolase
Soluble epoxide hydrolase enzyme is a promising therapeutic target for hypertension, vascular inflammation, pain and some other risk factors of cardiovascular diseases. The most potent sEH inhibitors reported in the literature are urea-based ones which often have poor bioavailability. In this study, in a quest for finding potent inhibitors of soluble epoxide hydrolase, some 4,6-disubstituted py...
