2-Azido-2-deoxy-3,4-O-iso­propyl­idene-2-C-methyl-D-ribono-1,5-lactone

The configuration of the title azide, C₉H₁₃N₃O₄, prepared from an arabinonolactone, is established by the X-ray crystal structure. The methyl group on the azide-substituted C atom is in a flagpole position. There are two mol­ecules in the asymmetric unit.
