The chiral nitrones derived from α-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-configuration. The nitrones 3-8 wer

Chiral nitrones derived from l -valine react with methyl acrylate to afford the corresponding diastereomeric 3,5-disubstituted isoxazolidines. The dibenzylsubstituted nitrone gave also 3,4-disubstituted isoxazolidine in 4% yield, additionally. The st

The new chiral terminal alkenes derived from cyclic acetals of D-erythrose 1-3 and D-threose 5, 6 were prepared. The alkenes 1, 2 and 5 react with chiral nitrones to afford the corresponding diastereomeric isoxazolidines 19-21. The stereoselectivity

The nitrones derived from cyclic acetals of D-erythrose 1a,b and D-threose 2a,b react with N- phenylmaleimide (3) to afford the corresponding diastereomeric isoxazolidines. The stereoselectivity is dependent on the steric hindrance of the nitrone. In
