The Intramolecular nitrone cycloadditions to Z and E chiral allyl ethers afford annulated isoxazolidines with good to excellent stereocontrol in favour of the C-5/C-5' anti isomers. The relative stereochemistry at the stereocenters in C-3/C-4 depends on the length of the chain connecting dipole and dipolarophile.

Abstract
The Intramolecular nitrone cycloadditions to Z and E chiral allyl ethers afford annulated isoxazolidines with good to excellent stereocontrol in favour of the C-5/C-5' anti isomers. The relative stereochemistry at the stereocenters in C-3/C-4 depends on the length of the chain connecting dipole and dipolarophile.
