A simple and high-yielding method for the preparation of 2,7-anhydro-β-d - ido-heptulopyranose (IDO) is described. It utilises the ability of molybdate ions to create the conditions for the skeletal rearrangement in the molecule of 2-C-branched aldose. This evidence is used in the synthesis of IDO from 2-C-(hydroxymethyl)-2,3:5,6-di-O-isopropylidene-d-gulofuranose in one step. The title compound is obtained in 95% yield.
