A route for the synthesis of bicyclo[3.1.0]hexane-derived conformationally restricted analogues of beta-arabinofuranosyl and alpha-galactofuranosyl rings is described. Advantage is taken of the pseudo-enantiomeric relationship between the two ring systems to develop a route that provides both targets from a single precursor. Key steps include a base-promoted ring contraction of an epoxy ketone obtained
