Аннотация: Previously unavailable 1,3-dialkyl-4,5-diaryl-4,5-dihydroxyimidazolidin-2-ones were obtained by the oxidation of 1,3-dialkyl-4,5-diaryl-4-imidazolin-2-ones with HNO3 (65 or 84% aq.). The scope of required 4-imidazolin-2-ones obtained from acyloins has been expanded, which provided preparation of new representatives of the title compounds.

Ключевые слова: 4,5-dihydroxyimidazolidin-2-ones, nitric acid, oxidation, 4-imidazolin-2-ones, diastereomers, acyloins, ureas.
