Methyl glycopyranosides with diallylamino and mesylate groups in relationship undergo an intramolecular reaction in which the amino group assists the replacement of the mesylate group by a nucleophile. Such a reaction may result in a 1,2-shift of the nitrogen atom depending on which carbon atom of the intermediate aziridinium ion is attacked by the nucleophile.
