Popis:	The carbamoylation of 4- and 5-hydroxyaminothiazolidine-2-thiones by methyl and 3,4-dichlorophenyl isocyanates leads to the corresponding hydroxyureas, which rearrange to 4- and 5-ureidothiazolidin-2-ones on heating in the presence of a base. Under these conditions, the hydroxyurea based on 5-hydroxylaminothiazolidin-2-one is converted to 5-ureidooxazolidin-2-one.
