1,3-Dipolar cycloaddition of 1,2-o-isopropylidene-α-d-xylopentadialdo-1,4-furanosenitrile oxide to some alkenes

The synthesis of five 3-(1,2-O-isopropylidene-α-D-xylofuranosyl)-5-substituted-2-isoxazolines obtained by 1,3-dipolar cycloaddition are described, as well as the intermediate products from the synthetic route. The physical and spectroscopic characterization of these compounds are reported.
