Аннотация: The reactions of ethyl 5,6,7,8-tetrafluoro-2-methylchromone-3-carboxylate with mercaptoacetic acid and 1,2-ethanedithiol afforded C(7)-substitution products. The above-mentioned chromone reacted with 2-mercaptoethanol to yield 7-mono- or 5,7,8-trisubstituted products depending on the reaction conditions. The reaction of 3-acetimidoyl-5,6,7,8-tetrafluoro-4-hydroxycoumarin with 2-mercaptoethanol afforded a 5,7,8-trisubstituted produect. The acyl-lactone rearrangement of mono- and trisubstituted chromones yielded the corresponding coumarins

METHYL PENTAFLUOROBENZOYLPYRUVATE -- DERIVATIVES -- 2-AMINOBENZENETHIOL
Аннотация: Transesterfication of bis(ethyl pentafluorobenzoylpyruvato)copper(II) gave bis(methyl pentafluorobenzoylpyruvato)copper(II) which underwent intramolecular cyclization to methyl 5,6,7,8-tetrafluoro-4-oxochromene-2-carboxylate. Treatment of bis(methyl pentafluorobenzoylpyruvato)copper(II) with hydrochloric acid afforded methyl pentafluorobenzoylpyruvate which reacted with 2-aminobenzenethiol, yielding 2-[4-(2-aminophenylthio)tetrafluorophenyl]benzothiazole. The reaction of bis(methyl pentafluorobenzoylpyruvato)-copper(II) with 2-aminobenzenethiol hydrochloride resulted in formation of 3-pentafluorobenzoylmethylene-3,4-dihydro-2H-1,4-benzothiazin-2-one. Methyl 5,6,7,8-tetrafluoro-4-oxochromene-2-carboxylate reacted with 2-aminobenzenethiol to give product of replacement of the 7-fluorine atom by 2-aminophenylthio group.

Аннотация: Perfluoro-3,4-epoxyoxolane and 3,4-epoxy-2- trifluoromethylpentafluorooxolane readily reacted with difunctional nucleophiles via opening of the oxirane ring and subsequent heterocyclization. Their reactions with thiourea and o-phenylenediamine gave new fluorine-containing fused heterocyclic compounds 2-amino-3a-hydroxy-4,4,6,6,6a-pentafluoro-3a,4,6, 6a-tetrahydrofuro[3,4-d][1,3]thiazole and 1,1,3,3-tetrafluoro- and 1-trifluoromethyl-1,3,3-trifluoro-1,3-dihydrofuro[3,4-b]quinoxalines, respectively. The molecular and crystalline structures of the products were determined by X-ray analysis.

Аннотация: 5,6,7,8-Tetrafluoro-4-hydroxycoumarin reacted with benzylamine under mild conditions to give a stable salt, while its refluxing with aniline or benzylamine in xylene afforded 5,6,7,8-tetrafluoro-4-phenyl(benzyl)aminocoumarins. Reactions of 3-acetyl(acetimidoyl)-5,6,7,8-tetrafluoro-4-hydroxycoumarins with benzylamine followed different pathways, depending on the solvent. Condensation at the acyl substituent can be accompanied by replacement of the F atom in position 7. 3-Acetylcoumarin formed a salt, while 3-acetimidoylcoumarin yielded a 7-monosubstituted product. 3-Acetyl(acetimidoyl)-5,6,7,8-tetrafluoro-4-hydroxycoumarins reacted with aniline to give only 5,6,7,8-tetrafluoro-4-hydroxy-3-(N-phenylacetimidoyl)coumarin

Аннотация: For the first time were obtained ethyl 2-(2-methoxy-3,4,5,6-tetrafluorobenzoyl)-3-oxobutanoate and ethyl 2-pentafluorobenzoyl-3-oxobutanoate and their copper chelates. The compounds were prepared by acylation of ethyl acetoacetate with 2-methoxy-3,4,5,6-tetrafluoro- and pentafluorobenzoyl chlorides. Cyclization of these ,'-dioxoesters afforded substituted chromones. 2-Methyl-5-methoxy-6,7,8-trifluoro-3-ethoxycarbonylchromone hydrolyzes depending on reaction conditions either to 5-hydroxy-2-methyl-6,7,8-trifluorochromone or to 5-hydroxy-2-methyl-6,7,8-trifluorochromone-3-carboxylic acid. Reaction with morpholine provided 7-substituted product, and with aqueous ammonia as a result of rearrangement forms 3-acetimidoyl-4-hydroxy-5-methoxy-6,7,8-trifluorocoumarin. Hydrolysis of the latter yields 3-acetyl-4-hydroxy-5-methoxy-6,7,8-triflu

Аннотация: The title compounds react with o-phenylenediamine and o-aminophenol at the ethoxalyl fragment to form heteryl-substituted quinoxalones and benzooxazinones, respectively. o-Aminobenzenethiol acts as both an S-nucleophile replacing the F atom and an N-nucleophile replacing the carbonyl group in the ethoxalyl fragment. Under more drastic conditions, cyclization proceeds to form benzothiazinones

Аннотация: Ethyl 5,6,7,8-tetrafluoro-4-oxo-2-phenyl-4H-chromene-3-carboxylate in reactions with primary amines is characterized by a chromone-coumarin rearrangement affording 3-[amino(phenyl)methylene]-6,7,8-trifluoro-2H-chromene-2,4(3H)-diones, and ethyl 4-oxo-2-phenyl-5,6,7,8-tetrafluoro-4H-chromene-3-carboxylate characteristically adds the amine at the C2 site of the flavone furnishing 3-amino-3-phenyl-2-(2,3,4,5-tetrafluoro-6-hydroxybenzoyl)acrylates which depending on the substituent at the amino group are capable of intramolecular cyclization into 3-[(alkylamino)(phenyl)methylene]-5,6,7,8-tetrafluoro-2H-chromene-2,4(3H)-dione or in the case of benzylamine substituent, into ethyl 1-benzyl-5-hydroxy-4-oxo-2-phenyl-6,7,8-trifluoro-1,4-dihydroquinoline-3-carboxylate. The main process in the reaction of tri- and tetrafluoroflavones with secondary amine (1-methylpiperazine) is the nucleophilic substitution at the C7 of flavone. In the reaction with 1,2-phenylenediamine 3-[(2-aminophenyl)amino]-3-phenyl-2-(2,3,4,5-tetrafluoro-6-hydroxybenzoyl)acrylate was obtained from tetrafluoroflavone and 1H-benzimidazol-2-yl(3,4,5-trifluoro-2-hydroxyphenyl)methanone, from trifluoroflavone
