Korotaev, D. L. Chizhov, I. B. Kutyashev, D. S. Yachevskii, O. N. Kazheva, O. A. Dyachenko, V. N. Charushin // Journal of Organic Chemistry. - 2006. - Vol. 71, № 12. - P4538-4543

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Polyhaloalkyl-substituted chromones, Y-pyrones, and B-furanones react with salicylaldehydes in the presence of piperidine to give a wide variety of fused 2H-chromenes in good yields. This novel annulation reaction presumably proceeds by a tandem intermolecular oxa-Michael addition and subsequent intramolecular Mannich condensation. ??

    Reactions of 3-(polyfluoroacyl)chromones with hydroxylamine : synthesis of novel R - containing isoxazole and chromone derivatives [Electronic resource] / M. I. Kodess, V. Ya. Sosnovskikh, V. S. Moshkin // Tetrahedron. - 2008. - Vol. 64, № 34. - P7877-7889 : рис. - Библиогр. : с. 7888-7889 (32 назв.)

Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Reaction of 3-(polyfluoroacyl)chromones with hydroxylamine free base proceeds via nucleophilic 1,4-addition followed by opening of the pyrone ring and subsequent cyclization to 4-(polyfluoroalkyl)-4H-chromeno[3,4-d]isoxazol-4-ols in good yields. On treatment with trifluoroacetic acid, the isoxazole ring of this annulated heterocyclic system opens to give 3-cyano-2-(polyfluoroalkyl)chromones, which were successfully hydrolyzed with concentrated H2SO4 to afford 3-carbamoyl-2-(polyfluoroalkyl)chromones. On the other hand, oximation of 3-(polyfluoroacyl)chromones with hydroxylamine hydrochloride occurs either at the carbonyl carbon atom connected to the RF group or at the C-2 atom to give 3-RFC(NOH)-chromones and 5-RF-4-salicyloylisoxazole oximes, respectively. The former were easily converted to 3-RF-4-salicyloylisoxazoles by simple heating in dimethyl sulfoxide.??

CHROMONES -- DILITHIOOXIMES -- 4H-CHROMENE-4-SPIRO-5'-ISOXAZOLINES; -- ALFA,BETA-UNSATURATED OXIMES -- BECKMANN REARRANGEMENT -- NITROSATION -- BROMINATION
Аннотация: Reactions of chromones with dilithiooximes proceed via nucleophilic 1,2-addition to give, on acidification, 4H-chromene-4-spiro-5-isoxazoline derivatives in high yields. On treatment with concentrated H2SO4 the isoxazoline ring of this novel spiroannulated heterocyclic system opens to give alfa,beta-unsaturated oximes, which undergo nitrosation, bromination, and the Beckmann rearrangement to the corresponding spiroisoxazolines and alfa,beta-unsaturated amides, respectively. The latter can be obtained directly by the Beckmann rearrangement of 4H-chromene-4-spiro-5`-isoxazolines

Similar reaction with ?-aminocrotononitrile gave 5-hydroxy-2-methyl-5-(polyfluoroalkyl)-5H-chromeno[4,3-b]pyridine-3-carbonitriles????

Аннотация: Starting from the corresponding cyclic 1,3-diketones or other precursors (cyclic ketones as well as lactones), several new salts and chelate complexes of fluorinated 1,3-dicarbonyls were obtained. Their preparative significance was demonstrated by straightforward syntheses of fluorinated pyrazoles, benzimidazoles and 1,7-ketoesters. The structure of a boron chelate of 2-(trifluoroacetyl)- cyclohexanone was investigated by X-ray diffraction

With aliphatic amines, 2-amino-3-(alkyliminomethyl)chromones are obtained in good yields. The reaction of 3-cyanochromone with o-phenylenediamine is reinvestigated and proof for the product structure and a possible reaction pathway are presented
