Abstract


It has been found that 4-nitrophenylglyoxal reacts with N-alkoxy-N’-arylureas and N-alkoxy-N’-alkylureas in acetic acid medium with the selective formation of the diastereomers of the 3-alkoxy-1,5-diaryl-4,5-dihydroxyimidazolidin-2-ones and 3-alkoxy-1-alkyl-5-aryl-4,5-dihydroxyimidazolidin-2-ones with sic-orientation of OH-groups. The X-ray structural analysis of 3-propyloxy-4S,5S-dihydroxy-1-methyl-5-(4-nitrophenyl)imidazolidin-2-one and of 3-n-butyloxy-4S,5S-dihydroxy-1-(4-methylphenyl)-5-(4-nitrophenyl)imidazolidin-2-one has demonstrated the structural parameters of these compounds.
