Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Alkyl 2-benzylidene-2-polyfluoroacylacetates react with urea and thiourea to yield 5-ethoxycarbonyl-4-fluoroalkyl-4-hydroxy-6-phenylhexahydropyrimidin-2-ones and -2-thiones and with guanidine sulfate to form 2-amino-5-ethoxycarbonyl-4-fluoroalkyl-6-phenyl-1,6-dihydropyrimidines and 3,6-diethoxycarbonyl-2,7-difluoroalkyl-4,5-diphenyl-4,5-dihydro-1H-pyrido[1,2-a]pyrimidines, and they react with phenylhydrazine to afford 4-alkoxycarbonyl-3-fluoroalkyl-3-hydroxy-1,5-diphenylpyrazolidines. Hydrazine hydrate catalyzes the formation of 3,5-diethoxycarbonyl-2,6-difluoroalkyl-2,6-dihydroxy-4-phenyltetrahydropyrans. When treated with anhydrous hydrazine and o-phenylenediamine, these esters cleave to form the products of condensation of fluoroacyl ester and benzaldehyde with diamines.

HYDRAZINES -- MOLECULAR STRUCTURE -- ISOMERIC PYRAZOLES;
Аннотация: The reaction between 2-trifluoroacetylcycloalkanones and methylhydrazine or phenylhydrazine exclusively yields 3-CF3-pyrazoles. When the chain length of the polyfluorinated substituent in RFC(O) group increases, 5-RF-pyrazoles are isolated. The reaction of 2-trifluoroacetylcyclohexanone with 2-hydrazinopyradine gives 5-hydroxypyrazoline, an intermediate in the formation of 5-CF3-pyrazoles. The regiochemistry of the condensation is probably controlled by the nucleophilicity of the terminal nitrogen in the mono substituted hydrazines and by the steric requirements of the RF group in the 1,3-diketones. Polymethylene chain containing pyrazoles obtained from the 1,3-diketones in question and hydrazine prefer the 3-RF tautomeric form, irrespective of carbocyclic ring size and polyfluoroalkyl group chain length.

Similar reaction in dioxane leads to 3-[3,3,3-trifluoro-2-(phenylhydrazono)propyl]-1-phenyl-1H-pyrazole-5-carboxylic acid. A strong solvent influence on the reaction route was also found for 6-(trifluoromethyl)comanic acid derivatives

    Synthesis of fluorinated 2(3)-arylhydrazones of 1,2,3-tri(1,2,3,4-tetra)carbonyl compounds and their heterocyclization reactions [] / Ya. V. Burgart, A. S. Fokin, O. G. Kuzueva, O. N. Chupakhin, V. I. Saloutin // Journal of Fluorine Chemistry. - 1998. - Vol. 92, № 2. - С. 101-108
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: New fluorinated 2-arylhydrazones of 1,2,3-triketones, 2-arylhydrazone-1,2,3-diketo esters and 3-arylhydrazone-1,2,3,4-triketo esters have been prepared by the coupling of fluorine-containing 1,3-keto esters, 1,3-diketones, acyl(aroyl)pyruvic esters and their chelates with aryldiazonium chlorides. The arylhydrazones react with hydrazine hydrate, phenylhydrazine, thiosemicarbazide and hydroxylamine to form the corresponding pyrazole and isoxazole derivatives. Interaction of 3-arylhydrazone-1,2,3,4-diketo esters with o-phenylenediamine results in quinoxaline products. Intramolecular cyclization of the arylhydrazones with pentafluorophenyl substituents leads to cinnolone derivatives

Аннотация: 3-Ethoxy- and 3-arylaminomethylidene-2,4-dioxo-4-pentafluorophenylbutanoates undergo cyclization by the action of hydrazine hydrate and phenylhydrazine to give ethyl 4-pentafluorobenzoylpyrazole-5-carboxylates.

Аннотация: 3-Trifluoromethyl-substituted 4-nitrosopyrazolines and 4-nitrosopyrazoles were prepared by a one-pot synthesis from trifluoromethyl-containing 1,3-diketones, sodium nitrite in acetic acid, and hydrazines (hydrazine hydrate, methylhydrazine). 3-Trifluoromethylpyrazolines can be converted to pyrazoles on heating. The use of phenylhydrazine in these reactions led to the formation of regioisomeric 4-hydroxyimino-5-(trifluoromethyl)pyrazoline. The structure of heterocycles synthesized was established using X-ray diffraction study, 1H and 19F NMR spectroscopy. The obtained products exhibited considerable tuberculostatic activity
