## Abstract Asymmetric 1,3‐dipolar cycloadditions of chiral derivatives of the nitrile oxides **3a**–**3c** derived from (2__R__)‐bornane‐10,2‐sultam, (2__R__)‐10‐(dicyclohexylsulfamoyl)isoborneol, and (1__R__)‐8‐phenylmenthol, to either (__E__)‐stilbene **4** or dimethyl fumarate **5**, leading to
## Abstract The efficient preparation of the chiral nitrile oxide derived from N‐glyoxyloyl‐(2__R__)‐bornane‐10,2‐sultam is presented. The nitrile oxide was trapped in situ with substituted olefins as dipolarophiles to furnish optically active 2‐isoxazolines. Chirality 13:629–630, 2001. © 2001 Wile
