The title compounds are obtained by three different methods. The aminothiocarbonylthiolation of barbituric acids 1 and aminouracil (5) can be accomplished in one step by reaction with thiuram disulfides in the presence of potassium carbonate. On the other hand, compounds 4 can be obtained via the salt of chloro derivative 2 or the corresponding iodonium ylides 3. The aminouracil derivative 7 was obtained
