Jm. Andres et al., A practical stereoselective synthesis of both enantiomers of threo- and erythro-beta-hydroxy norvaline from (S)-serine derivatives, TETRAHEDRON, 56(11), 2000, pp. 1523-1531
The four enantiopure diastereoisomers of beta-hydroxy norvaline have been p
repared from L-serine in moderate chemical yield. The method is based on th
e diastereoselective addition of different organometallics to easily access
ible serinal derivatives. (C) 2000 Elsevier Science Ltd. All rights reserve
