Deoxy glycals can be synthesized from a mannitol-derived C2-symmetric diene diol by using the tandem RCM/isomerization approach. Incorporation of a ruthenium-catalyzed dehydrogenative silylation step into the reaction sequence is possible. Thus, an orthogonally protected 3-deoxy glycalresults via a tandem RCM/hydrosilylation/isomerization sequence. All ruthenium-catalyzed steps of this tandem sequence
