4-Trifluoromethyl-6-phenyl-2-chloro-3-cyanopyridine was synthesized, and its molecular-crystal structure was established. The chlorine atom was replaced by amino, mercapto, thiocyanato, and azido groups. The possibility of the direct amination of 4-trifluoromethyl-6-phenyl-3-cyano-2-pyridone by the action of hexamethylphosphoric triamide (HMPT) was demonstrated.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1233–1237, September, 1987. 相似文献

The literature data for the period 1973–1985 on the synthesis, on the basis of cyclohexane-1,3-diones and their derivatives, of heterocyclic compounds that contain a 3-oxocyclohexene structural fragment or are formed as a result of a change in the cyclohexane ring are examined.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 723–738, June, 1988. 相似文献

The conditions for the formation of amides of 4-keto acids, 2-oxo-5-hydroxypyrrolidlnes, 2-oxo-2,3-dihydropyrroles, or 2-oxo-5-aminotetrahydrofurans by reaction of a Δβ,γ-butenolide with primary amines were determined. The reaction with primary aliphatic amines — benzylamine and methylamine — in ethanol gives 2-oxo-5-hydroxypyrrolidines, while reaction with benzylamine in benzene gives the amide of a 4-keto acid. 2-Oxo-5-anilinotetrahydrofuran is formed in the reaction with aniline. 相似文献

The literature data on the synthesis of partially hydrogenated heterocyclic compounds containing a 3-oxocyclohexene structural fragment condensed with five-, six-, or seven-membered oxygen-, nitrogen-, and sulfur-containing heterorings from cyclohexane-1,3-diones and their derivatives are examined in this review. 相似文献

4-Bromo-5-(4-hydroxymethyltriazolyl)pyridazin-3-ones have been obtained for the first time by the reaction of 5-azido-4-bromopyridazin-3-ones with propargyl alcohol. They have been converted into 4-bromo-5-(4-halogenomethyltriazolyl)pyridazin-3-ones. 相似文献

,-Dibromo--('-carbethoxyacetony)-,-butenolide (I) reacts with amines in diethyl ether solution to give -bromo-amino--('-carbethoxyacetony)-,-butenolides. Compounds n are converted to -bromo-amino--('-carbethoxyacetony)-,-butenolides on reaction with amines. The corresponding arylhydrazones (VI and VII) are obtained by the reaction of I and II with p-nitro- and 2,4-dinitrophenylhydrazines. Compound I reacts with phenylhydrazine to give furopyridazine VIII.See [1] for communication IV.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 867–871, July, 1972. 相似文献

A convenient method is proposed for the synthesis of new derivatives of the pyridine series, alkyl N-(2-oxo-3-pyridyl)carbamates (IIa-i, IVa-j), in the reaction of 7-trifluoromethyl-5-phenyl-2-oxooxazolo[5,4-b]pyridines (I, IIIa-j) with alcohols.Riga Technical University, Riga LV-1048.
