Аннотация: The data on 6-fluorо-1,4-dihydroquinolin-4-oxo-3-carboxylic acids and their structural analogues accumulated in the literature for the last 10–15 years are reviewed. Synthetic approaches to the quinolone system, as well as all kind of structural modifications by incorporating substituents into 1–8 positions or by means of annelation have been discussed. The “structure-activity” relationships for antibacterial fluoroquinolones, as well as the data on other types of biological activity for the family of bi- and polycyclic fluoroquinolones are presented. The formation of complexes of fluoroquinolones with metals and their applications have been considered. The bibliography

Аннотация: In the reaction of N-methylquinoxalinium iodide with acetylacetone at −30 °C, the formation of 3-acetyl-2,4-dimethyl-3a,4,9,9a-tetrahydrofuro[2,3-b]quinoxaline has been recorded by 1H NMR spectroscopy, this being a regioisomer of the 3-acetyl-2,9-dimethyl-3a,4,9,9a-tetrahydro[2,3-b]quinoxaline formed in this reaction at temperatures above −10 °C. σ-Adducts of the N-methylquinoxalinium cation with alcohols, amines, and β-diketones have also been identified, and their role in cyclizations leading to the annelation of a furan ring is discussed.

Аннотация: 1- and 4-mono- as well as 1,4-disubstituted thiosemicarbazies undergo cyclization reactions upon treatment with N-alkylpyrazinium and quinoxalinium salts to give N-aminosubstituted imidazo[4,5-b]pyrazines and imidazo[4,5-b]quinoxalines, respectively. Thiosemicarbazides containing substituents in the 2-position react with N-alkylquinoxaline salts to give 1,2,4-triazino[5,6-b]quinoxalines after cyclization.
