Abstract
Reaction of 2-thioxo or 2-oxo-1,3-dialkyl-4,5-dihydroxy-4,5-diphenylimidazolidines with KSCN in acidified MeOH affords 4,6-dialkyl-3a,6a-diphenyltetrahydro-2H-imidazo[4,5-d]oxazole-2,5(3H)-dithiones or 4,6-dimethyl-3a,6a-diphenyl-2-thioxotetrahydro-2H-imidazo-[4,5-d]oxazol-5(3H)-one, whose structure was proved by X-ray diffraction.
