title: Synthesis of bicyclo[3.1.0]hexane derivatives as conformationally restricted analogues of beta-arabinofuranosyl and alpha-galactofuranosyl rings.
abstract: 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 from cyclohexane-1,4-dione to give the bicyclo[3.1.0]hexane ring system and a late stage resolution involving esterification with O-acetyl-(S)-mandelic acid.
