| Abstract/Summary |
Ethyl 4-(1-ethyl-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)-2,4-dioxobutyrate, ethyl 5-(1-ethyl-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)pyrazole-3-caboxylate and their acid hydrozide derivatives have been prepared and reacted with hydrazines, o-phenylenediamine, triethyl orthoformate, carbon disulfide, and thiosemicarbazides in order to obtain some new 3-substituted quinolin-2-ones as: pyrazolines, isoxazolines, imidazoles, pyrazolotriazines, thiadiazoles, and triangles. All the newly prepared compounds revealed the potent effect on increasing reactivity of cellobimse. The structure of the new compounds was established upon their elemental analyses, IR, 1H NMR, and mass fragmentation spectra.
