The reaction of 3-(4-bromoacetylphenyl)-1-methylquinolin-2(1Н)-one with pyridine and 4-methylpyridine has afforded the corresponding pyridinium salts. Condensation of 4-methyl-1-{2-[4-(1-methyl-2-oxo-1,2-dihydroquinolin-3-yl)phenyl]-2-oxoethyl}pyridinium bromide with 4-dimethylaminobenzaldehyde has given a new biscyanine dye, 1-{1-[4-(1,2-dihydro-1-methyl-2-oxo-3-quinolinyl)benzoyl]-2-[4-(dimethylamino)-phenyl]ethynyl}-4-{2-[4-(dimethylamino)phenyl]ethynyl}pyridinium bromide. Its electronic spectrum has been analyzed, and quantum-chemical simulation of spatial and electronic structure of its possible isomers has been performed. 相似文献

The Meerwein reaction of 1-methylquinolin-2(1H)-one with 4-acetylbenzenediazonium chloride gave 3-(4-acetylphenyl)-1-methylquinolin-2(1H)-one which was brominated to 3-[4-(2-bromoacetyl)phenyl]-1-methylquinolin-2(1H)-one. The latter reacted with pyridine, 4-methylpyridine, quinoline, benzo[f]quinoline, and triphenylphosphine to afford the corresponding quaternary salts, and its reactions with thioacetamide, thiourea, 2-aminopyridine, and 2-aminopyrimidine led to the corresponding thiazole, imidazo[1,2-a]pyridine, and imidazo[1,2-a]pyrimidine derivatives containing a 2-oxoquinoline fragment. 3-(4-{2-[2-(Arylmethylidene)-hydrazinyl]-1,3-thiazol-4-yl}phenyl)-1-methylquinolin-2(1H)-ones were obtained by condensation of 3-[4-(2-bromoacetyl)phenyl]-1-methylquinolin-2(1H)-one with thiosemicarbazide and aromatic aldehydes. 相似文献

3-(4-Acetylphenyl)-2H-chromen-2-one was obtained from 4-acetylphenyldiazonium chloride in the conditions of Meerwein reaction. Reactions of 3-[4-(2-bromoacetyl)phenyl]-2H-chromen-2-one with pyridine, 4-methylpyridine, quinoline, benzo[f]quinoline, and triphenylphosphine afforded quaternary salts, and with thioacetamide, thiourea, 2-aminopyridine, 2-aminopyrimidine, and 6-aminopurine provided the corresponding derivatives of thiazole, imidazo[1,2-a]pyridine, imidazo[1,2-a]pyrimidine, imidazo[2,1-i]purine. In the reaction of the same bromo derivative with thiosemicarbazide and aromatic aldehydes a thiazole ring is built and the corresponding hydrazones are formed. 相似文献
