New products from the reactions of 4,5-dihydroxyimidazolidin-2-ones with sulfonamides

For the first time the interactions of N-alkyl- and N,N′-dialkyl-4,5-dihydroxyimidazolidin-2-ones with sulfonamides have been studied and as a result N-alkyl- and N,N′-dialkyl-4(5)-aryl(alkyl)sulfonyliminoimidazolidin-2-ones and 4,4′-sulfonyldiiminobis(N,N′-dimethylimidazolidin-2-one) have been synthesized.
