The stereocontrolled synthesis of β-hydroxy-α-amino acids from O-benzyl D- and L-serine, by the use of 4,5-disubstituted oxazolidin-2-ones as chiral intermediates, is presented as a suitable alternative to the known procedures.The reported synthesis of both enantiomers of threo-3-hydroxyglutamic acid and (2S,3R)-3-hydroxyproline together with a flexible and stereodivergent preparation of threonine analogues is discussed as an example of the versatility of the present approach.
