A process for preparing specific 1-substituted 5-hydroxy-imidazoline-2,4-diones by reacting glyoxylic acid with N-substituted ureas is provided, where this process is carried out in a 10-80% strength aqueous solution and in the presence of an acid catalyst. The 1-substituted 5-hydroxy-imidazoline-2,4-diones can subsequently be converted in a further reaction step to give 1-substituted 5-alkoxy-imidazoline-2,4-diones.

The ozonolysis of uracils unsubstituted at the 1-position gave new 1-acyl-5-hydroxyhydantoins and 5-hydroxyhydantoins in water, while that of 1-substituted uracils gave the corresponding 5-hydroxyhydantoins in low yields.The structure of 1-acetyl-5-hydroxy-5-methylhydantoin was determined by X-ray crystallography.
