3-Hydroxy-, 3-Alkoxy- and 3-Amino-2-thioxooxazolidine-4-ones from 6-Thioxoperhydro-1,5,2-dioxazine-3-ones

Geffken, Detlef

, p. 1008 - 1014 (2007/10/02)

1,1'-Thiocarbonyldiimidazole converts N-substituted glycolohydroxamic acids (1) at room temperature into 6-thioxoperhydro-1,5,2-dioxazine-3-ones (2 B), which are highly reactive heterocyclic compounds.In the presence of primary amines (3), benzyloxyamine (6a), hydroxylamine (6b) and hydrazines (8a-d) ring transformation of 2 B occurs, yielding 2-thioxooxazolidine-4-ones of type 5, 7 and 9. - Key words: Glycolhydroxamic Acids, 1,1'-Thiocarbonyldiimidazole, 6-Thioxoperhydro-1,5,2-dioxazine-3-ones, Ring Transformation
