Synthesis of a partially benzylated derivative of the anhydro-d-altro-heptulose found in Coriaria japonica A

A partially benzylated derivative of the anhydro-d-altro-heptulose found in Coriaria japonica A, which is a synthetically useful unit, was successfully synthesized from a d-mannose derivative by a novel synthetic approach involving an intramolecular O-ketopyranosylation.
