TL;DR: A series of quaternary salts were obtained by reacting 3-(4-bromoacetylphenyl)-1-methylquinolin-2(1H)-one with Py, 4-methylpyridine, quinoline, benzo[f]quinoline, and triphenylphosphine as discussed by the authors.
Journal ArticleDOI
Synthesis of nitrogen-containing heterocycles on the basis of 3-(4-acetylphenyl)-1-methylquinolin-2(1 H )-one
O. V. Elenich,Roman Lytvyn,O. V. Skripskaya,O. S. Lyavinets,Kh. E. Pitkovych,P. I. Yagodinets,Mykola D. Obushak +6 more
TL;DR: The Meerwein reaction of 1-methylquinolin-2(1H)-one with 4-acetylbenzenediazonium chloride gave 3-(4-βromoacetylphenyl)-1-miquelin-2.1H-one which was brominated to 3-[4-(2-bromometyl)phenyl]-1-methylquinoline-2 (1H]-one by condensation with thiosemicarbazide and aromatic aldehydes as mentioned in this paper.
Journal ArticleDOI
4-(4-Acethylphenyl)-3-hydroxycoumarin in the Synthesis of Nitrogen-containing Heterocycles with a Neoflavonoid Moiety
P. I. Yagodinets,O. V. Rusnak,Roman Lytvyn,O. V. Skrypska,Kh. Ye. Pitkovych,Mykola D. Obushak +5 more
TL;DR: In this paper, it was shown that 4-(4-acetylphenyl)- and 4-(2-bromoacetyl)phenyl]-3-hydroxy-2H-chromen-2-ones can be used in three-component reactions to form a thiazole ring.
Journal ArticleDOI
New biscyanine dye based on 1-{2-oxo-2-[4-(2-oxo-2H-chromen-3-yl)phenyl]ethyl}-4-methylpyridinium bromide. Electron transitions and electronic spectra
