A tandem Mannich addition–palladium catalyzed ring-closing route toward 4-substituted-3(2H)-furanones
A facile route towards highly functionalized 3(2H)-furanones via a sequential Mannich addition-palladium catalyzed ring closing has been elaborated. The reaction of 4-chloroacetoacetate esters with imines derived from aliphatic and aromatic aldehydes under palladium catalysis afforded 4-substituted furanones in good to excellent yields. 4-Hydrazino-3(2H)-furanones could also be synthesized from...
متن کاملSynthesis and Anticonvulsant Activity Evaluation of 3-alkoxy-4-(4- (hexyloxy/heptyloxy)phenyl)-4H-1,2,4 -triazole
A series of 3-alkoxy-4-(4-(hexyloxy/heptyloxy) phenyl)-4H-1,2,4-triazole was synthesized. The anticonvulsant effect and neurotoxicity of the compounds were calculated with maximal electroshock (MES) test and rotarod tests with intraperitoneally injected mice. Among the synthesized compounds, compound 3-heptyloxy-4-(4-(hexyloxy) phenyl)-4H-1,2,4-triazole (5f) was the most active one and also had...
متن کاملPreparation of 4-Alkoxy-1-hydroxypyridine-2-thiones
Reactions of 2-chloro-4-fluoropyridine (8), 2-chloro-4-nitropyridine (9), and their corresponding N-oxides 7 and 3 with the n-heptanolate anion were investigated in three solvents. The desired 2-chloro-4-heptyloxypyridine-N-oxide (4a) was obtained most efficiently from 3 in DMSO. A reaction of 4a with AcSNa followed by deacetylation with MeONa gave the sodium salt of 4-heptyloxy-1-hydroxypyridi...

متن کاملNovel Porous Iron Molybdate Catalysts for Synthesis of Dimethoxymethane from Methanol: Metal Organic Frameworks as Precursors
As a novel performance, methanol gas conversion to dimethoxymethane (DMM) in one-step based on Fe-Mo-O (iron molybdate mixed oxides) catalysts with high surface area fabricated by metal organic frameworks (MOFs) precursors was improved. For this approach, at first, Fe(III) precursors (iron (III) 1,3,5-benzenetricarboxylate (MIL-100 (Fe) and iron terephthalate (MOF-...
