I. Blanarikova et al., Synthesis of chiral amino acid-derived nitrones and 1,3-dipolar cycloadditions with acrylic acid methyl ester, ARKIVOC, 2, 2001, pp. NIL_54-NIL_62
The chiral nitrones derived from alpha -amino acids react with acrylic acid
methyl ester to afford the corresponding diastereomeric isoxazolidines 9a-
d. The major products are in the C-3/C-4 erythro- and C-3/C-3a trans-config
uration. The nitrones 3-8 were prepared from the corresponding alpha -amino
aldehydes, starting from L-phenylalanine and L-valine.
