A diastereospecific method for the synthesis of individual enantiomers of 1S,5R- and 1R,5S-glycoluriles has been developed based on the α-ureidoalkylation of (S)/(R)-N-carbamoyl-α-amino acids with 4,5-dihydroxyimidazolidin-2-one.
Highly diastereoselective synthesis of 2-monosubstituted 1R,5S(1S,5R)-glycoluriles on the basis of S- and R-N-carbamoyl-α-amino acids

The reactions of 4,5-dihydroxyimidazolidin-2-one with chiral S- and R-N-carbamoyl-α-amino acids occur diastereoselectively with the formation of corresponding 1R,5S(1S,5R)-glycoluriles as predominant diastereomers; the absolute configuration is determined
