Abstract: | 3-Alkyl/Aryl-3-aminoquinoline-2,4-diones react with isothiocyanates to give 3a-alkyl/aryl-1,2,3,3a-tetrahydro-9b-hydroxy-2-thioxo-5H-imidazo-[4,5-c]quinolin-4(9bH)-ones. These compounds rearrange in an acidit environment to give novel 4-(2-aminophenyl)-1H-imidazole-2(3H)-thiones and 1,3-bis(2-(2,3-dihydro-2-thioxo-1H-imidazol-5-yl)phenyl)ureas. | ||||||||||
