Synthetic access to the first spirocyclopropyl iminosugar

The synthesis of the first spirocyclopropyl iminosugar has been achieved in six steps and 13% overall yield from commercially available 2,3,5-tri-O-benzyl-D-arabinose. The synthesis is based on an efficient two-step reaction involving the titanium-mediate
