Abstract: | 5-Hydroxyaminothiazolidine-2-thiones are oxidized in an alkaline medium to 5-hydroxyiminothiazolidine-2-thiones or undergo recyclization to derivatives of imidazolidine-2-thiones, depending on their structure. 4-Hydroxyaminothiazolidine-2-thiones break down under analogous conditions.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1143–1145, August, 1989. |
