SYNTHESIS -- PYRAZOLES -- TUBERCULOSTATIC ACTIVITY
Аннотация: Alkylation of polyfluoroalkyl-containing pyrazoles with 4-bromobutyl acetate in acetone in the presence of potassium carbonate leads to a mixture of isomeric 1-(4-acetoxybutyl)-3-fluoroalkyl- and 1-(4-acetoxybutyl)-5-fluoroalkylpyrazoles, which in a number of cases were successfully separated by HPLC. Deacylation in acidic medium with gaseous hydrogen chloride and in basic medium with gaseous ammonia leads to 1-(4-hydroxybutyl)pyrazoles, which manifest moderate tuberculostatic activity

3-AMINO-5-HYDROXYPYRAZOLE -- RECYCLIZATION -- PYRIDINES
Аннотация: The reactions of ethyl 2-ethoxymethylene-3-oxo-3-(polyfluoroalkyl) propionates with 3-amino-5-hydroxypyrazole result in ethyl 2,7-dihydroxy-7- (polyfluoroalkyl)-4,7-dihydropyrazolo[1,5-a]pyrimidin-6-carboxylates under mild conditions. These products undergo recyclization in refluxing ethanol to form ethyl 3-hydroxy-4-(polyfluoroalkyl)-1H-pyrazolo[3,4-b]pyridin-5-carboxylates, whereas in refluxing glacial acetic acid they are dehydrated to ethyl 2-hydroxy-7-(polyfluoroalkyl)pyrazolo[1,5-a]pyrimidin-6-carboxylates. The non-fluorinated ethyl 2-ethoxymethylene-3-oxo esters in the reactions with 3-amino-5-hydroxypyrazole in ethanol (or glacial acetic acid) under reflux form only ethyl 2-hydroxy-7-phenyl(hydroxy)pyrazolo[1,5-a]pyrimidin-6-carboxylates

TRIAZINE SYNTHESIS -- 1,3-DICARBONYL -- ISOMERISM
Аннотация: Azo coupling of 1,3-dicarbonyl compounds with tetrazolyl-5-diazonium chloride is used to develop a convenient one-step procedure for the synthesis of 4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines. In contrast to nonfluorinated analogs, 7-hydroxy-7-polyfluoroalkyl-4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines undergo a ring-chain isomerism resulting from the cleavage at the C7 - N7a bond. A distinctive feature of nonfluorinated 4,7-dihydrotetrazolo[5,1-c][1,2,4] triazines is the possibility to dehydration, which is accompanied by an azide rearrangement due to the tetrazole ring cleavage with the formation of tetrazolo[1,5-b][1,2,4]triazines

Deacylation of these compounds under acidic conditions gives the corresponding 1-(4-hydroxybutyl)- and 2-(4-hydroxybutoxy)-substituted quinoxalines. The structures of compounds synthesized were established by X-ray crystallography, IR spectroscopy, 1H and 19F NMR spectroscopy, GLC-MS

ALIPHATIC AND AROMATIC AMINES -- ETHYLENEDIAMINE -- FORMALDEHYDE
Аннотация: 6-Polyfluoroalkyl-2-thiouracils react with formaldehyde and primary amines in EtOH (MeCN) at 2-mercapto and 3-amino groups to yield pyrimido[2,1-b][1,3,5] thiadiazines via the multicomponent double Mannich reaction. The structure of 3-benzyl-8-nonafluorobutyl-3,4-dihydro-2H,6H-pyrimido[2,1-b][1,3,5] thiadiazin-6-one was studied by the X-ray diffraction analysis. The use of ethylenediamine in these reactions yields 3,3′-ethane-1,2-diyl- bis(pyrimido[2,1-b]thiadiazinone) as a result of the bis-double Mannich cyclocondensation. 8-Polyfluoroalkyl-pyrimido[2,1-b]thiadiazines exhibit weak tuberculostatic activity

BETA-KETO ACIDS -- OMEGA-PHENYLENEDIAMINE -- ENAMINES -- LIGANDS -- COPPER(ii) COMPLEXES -- NICKEL(ii) COMPLEXES -- COBALT(ii) COMPLEXES -- ORGANOFLUORINE COMPOUNDS
Аннотация: Diethyl 2,2' [1,2-phenylenebis(aminomethylidene)]bis(3-oxo-3-polyfluoroalkylpropionates) were synthesized by the condensation of a double excess of ethyl 2-ethoxymethylidene- 3-oxo-3-polyfluoroalkylpropionates with o-phenylenediamine. The use of equimolar ratios of the starting reactants affords ethyl 2-[(2-aminophenyl)aminomethylidene]-3-oxo- 3-polyfluoroalkylpropionates from which nonsymmetric biscondensation products were synthesized by the reaction with related reactants containing different polyfluoroalkyl substituent. The copper(II), nickel(II), and cobalt(II) complexes were obtained on the basis of new ligands.

BENZIMIDAZOLES -- ETHYL -- PROPIONATES
Аннотация: Cyclization of ethyl 2-ethoxymethylidene-3-oxo-3-polyfluoroalkylpropionates with benzimidazol-2-amine in boiling 1,4-dioxane followed two concurrent pathways with participation of fluoroacyl and ethoxycarbonyl fragments and formation of, respectively, ethyl 4-hydroxy-4-polyfluoroalkyl-1,4-dihydropyrimido-[1,2-alfa]benzimidazole-3-carboxylates and 3-polyfluoroacylpyrimido[1,2-alfa]benzimidazol-4-ols. Dihydropyrimido[1,2-alfabenzimidazole derivatives undergo dehydration to give ethyl 4-(polyfluoroalkyl)pyrimido[1,2-alfa]benzimidazole-3-carboxylates, whereas the hydroxy group in 3-polyfluoroacylpyrimido[1,2-a]benzimidazol-4-ols is capable of being replaced by the amino group of the second benzimidazole molecule with formation of 4-(1H-benzimidazol-2-ylamino)-3-polyfluoroacylpyrimido[1,2-alfa]benzimidazoles.
