Abstract: | 3-Butyl-3-aminoquinoline-2,4-diones react with isothiocyanates to give novel 3a-butyl-9b-hydroxy-hexahydro-imidazo[4,5-c]quinolin-2-ones . These compounds rearrange in an acidit environment to give (E)- and/or (Z)-4-butylidene-2-thioxo-1´H-spiro[imidazoline-5,3´-indole]-2,2-diones. | ||||||||||
