A practical stereoselective synthesis of both enantiomers of Threo- and Erythro-β-hydroxy norvaline from (S)-serine derivatives

The four enantiopure diastereoisomers of β-hydroxy norvaline have been prepared from L-serine in moderate chemical yield. The method is based on the diastereoselective addition of different organometallics to easily accessible serinal derivatives. (C) 2000 Elsevier Science Ltd.
