Highly diastereoselective synthesis of 2-monosubstituted 1 R,5 S(1 S,5 R)-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 1 R, 5S(1S,5R)-glycoluriles as predominant diastereomers; the absolute configuration is determined for three stereoisomers by X-ray diffracti...

Summary: | 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 1
R,
5S(1S,5R)-glycoluriles as predominant diastereomers; the absolute configuration is determined for three stereoisomers by X-ray diffraction analysis. |
