Synthesis of 2-thioxoimidazolines via reaction of 1-unsubstituted 3-aminoquinoline-2,4-diones with isothiocyanates

Original language description

3-Alkyl/aryl-3-amino-1H,3H-quinoline-2,4-diones react with alkyl/aryl isothiocyanates to give 3a-alkyl/aryl-1,2,3,3a-tetrahydro-9b-hydroxy-2-thioxo-5H-imidazo[4,5-c]quinolin-4(9bH)-ones in high yields. These compounds rearrange in boiling acetic acid orconcd hydrochloric acid to give novel 4-(2-aminophenyl)-1H-imidazole-2(3H)-thiones, 1,3-bis(2-(2,3-dihydro-2-thioxo-1H-imidazol-5-yl)phenyl)ureas and minor N-(2-(2,3-dihydro-2-thioxo-1H-imidazol-4-yl)phenyl)acetamides. In the presence of ethanol, the starting compounds rearrange in boiling acetic acid to give ethyl 2-(2,3-dihydro-2-thioxo-1H-imidazol-4-yl)phenylcarbamates. All compounds were characterized by their H-1, C-13, IR and MS spectra and some of them also by N-15 NMR data. The structures of twocompounds were supported by single-crystal X-ray diffraction
