摘要：
Hydantoins, thiohydantoins, and glycocyamidines have been prepared in moderate to excellent yields at room temperature under solvent-free conditions. 3N-amino and carboamide derivatives of hydantoin (7-8) were prepared in single step by condensing benzil with semicarbazide and biuret respectively.
