چکیده انگلیسی
1-Substituted 3a-alkyl/aryl-9b-hydroxy-3,3a,5,9b-tetrahydro-1H-imidazo[4,5-c]quinoline-2,4-diones and 3â²-substituted 3-alkyl/aryl-3-ureido-1H,3H-quinoline-2,4-diones react in boiling acetic acid to give 2-alkyl/aryl-1H-indol-3-yl-ureas and/or 1,3-bis[2-(2-oxo-2,3-dihydro-1H-imidazol-4-yl)-phenyl]-ureas. By the action of hydrochloric acid, the first of them rearrange to give 4-(2-aminophenyl)-1,3-dihydroimidazol-2-ones. The structure of 1,3-bis[2-(2-oxo-2,3-dihydro-1H-imidazol-4-yl)-phenyl]-ureas was confirmed by their synthesis. All compounds were characteried by their 1H NMR, 13C NMR, IR spectra, atmospheric pressure chemical ioniation mass spectra, and some of them also by 15N NMR spectroscopic data.
