Abstract: A synthesis of the title system from D-gahCtOSe has been achieved. The racemic galactose 1, 2, 3, 4-bisacetonide is expanded to a C7 heptulose, which is then extended to an undecose by a Lewis acid catalyzed cyclocondensation reaction. Racemic galactose was synthesized from furfural by a similar cyclocondensation reaction.
