Аннотация: Condensation of fluorinated 3-oxo esters or 1,3-diketones with benzaldehyde and (thio)urea results in the diastereoselective formation of 4-fluoroalkyl-4-hydroxy-2-oxo(thioxo)-6-phenyl-hexahydropyrimidine-5-carboxylates from which by dehydration under acidic conditions the corresponding 6-fluoroalkyl-2-oxo(thioxo)-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylates were obtained. Under the same conditions, hexafluoroacetylacetone furnishes 4,6-dihydroxy-4,6-di(trifluoromethyl)-hexahydropyrimidin-2-one. Some further reactions of these pyrimidine derivatives leading to fused heterocycles are described.????

    CuCl2 induced reactions of 6-ethynyl- and 6-cyano-5-aryl-2,2-bipyridines with various N- and O-nucleophiles in comparison with the reactions of relative 1,2,4-triazines [Text] / A. M.

Аннотация: Meanwhile 5-aryl-6-cyano-2,2-bipyridines are very stable towards various nucleophiles, addition copper(II) chloride to the reactional mixture facilitates nucleophilic addition to the cyano group dramatically. The cyanobipyridines react easily with water, methanol, ethanolamine in the presence of CuCl2 yielding well-crystallized complexes containing carboxylates, carboximidates or carboxamidines as ligands. 5-Cyano-1,2,4-triazines are more active in the reactions due to higher electron-withdrawing properties of this heterocycle. Due to the same reason acetylene moiety of 5-ethynyl-3-pyridyl-1,2,4-triazine adds water quite easily but in the presence of copper chloride as well

THREE-COMPONENT REACTIONS -- AMMONIUM ACETATE
Аннотация: Reactions of 3-(polyfluoroacyl)chromones with acetoacetamide and ethyl acetoacetate in the presence of ammonium acetate proceed at the C-2 atom of the chromone system with pyrone ring-opening and subsequent cyclization to 5-salicyloyl-2-methyl-6-(trifluoromethyl)nicotinamides, ethyl 5-salicyloyl-2-methyl-6-(trifluoromethyl)nicotinates, and ethyl 5-hydroxy-2-methyl-5-(polyfluoroalkyl)-5H-chromeno[4,3-b]pyridine-3-carboxylates. Similar reaction with ?-aminocrotononitrile gave 5-hydroxy-2-methyl-5-(polyfluoroalkyl)-5H-chromeno[4,3-b]pyridine-3-carbonitriles????

Аннотация: 3-Arylhydrazono-4-polyfluoroalkyl-2,4-dioxobutanoates reacted with hydrazines to give ethyl 4-aryldiazeno-3-polyfluoroalkyl-1H-pyrazole-5-carboxylates, while analogous reactions of ethyl 3-arylhydrazono-4-pentafluorophenyl-2,4-dioxobutanoates resulted in the formation of 4-aryldiazeno-3-pentafluorophenyl-1,2-dihydropyridazine-5,6-diones or 6-aryl-7,8,9,10-tetrafluoro-2-phenyl-2,4a,6,10b-tetradropyridazo[4,3-c]cinnoline-3,4-diones, depending on the conditions. Cyclocondensation of ethyl 3-arylhydrazono-4-polyfluoroalkyl(or pentafluorophenyl)-2,4-dioxobutanoates with ethylenediamine led to 3-[1-arylhydrazono-2-oxo-2-polyfluoroalkyl(or pentafluorophenyl)ethyl]-5,6-dihydropyrazin-2(1H)-ones, and 3-[1-arylhydrazono-2-oxo-2-polyfluoroalkyl(pentafluorophenyl)ethyl]benzoxazin-2-ones were formed in the condensation with o-aminophenol. Pentafluorophenyl-substituted heterocycles were found to undergo intramolecular ring closure to give 3-hetaryl-substituted 1-aryl-5,6,7,8-tetrafluoro-1,4-dihydrocinnolin-4-ones. The reactions of ethyl 3-arylhydrazono-4-pentafluorophenyl-2,4-dioxobutanoates with o-aminobenzenethiol gave 3-[7-(2-aminophenylsulfanyl)-1-aryl-5,6,8-trifluoro-4-oxo-1,4-dihydrocinnolin-3-yl]benzothiazin-2-ones; 8a-hydroxy-11,12,13,14-tetrafluoro-10-(4-methoxyphenyl)-2,3,4,5,6,7,8a,10-octahydropyrazino[1?,2?:4,5][1,4]diazepino[6,7-c]cinnolin-8-one was isolated in the condensation of ethyl 3-(4-methoxyphenylhydrazono)-4-pentafluorophenyl-2,4-dioxobutanoate with N-(2-aminoethyl)ethane-1,2-diamine ??

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. The reaction of 3-ethoxymethylidene-2,4-dioxo-4-pentafluorophenylbutanoate with o-phenylene-diamine leads to formation of 3-[2-(2-aminophenylamino)-1-pentafluorobenzoylethenyl]-1,2-dihydroquinoxa-lin-2-one. 3-Arylaminomethylidene-2,4-dioxo-4-pentafluorophenylbutanoates react with o-phenylenediamine to afford 3-(1-aryl-5,6,7,8-tetrafluoro-4-oxo-1,4-dihydroquinolin-3-yl)-1,2-dihydroquinoxalin-2-ones and/or 3-(2-arylamino-1-pentafluorobenzoylethenyl)-1,2-dihydroquinoxalin-2-ones
