A Ru-catalyzed olefin migration reaction of chiral cyclic acetal is reported. The reaction generates cyclic enol acetal in a highly chemoselective manner. A variety of O,O- and N,O-acetals participated in the reaction with conservation of the stereochemical integrity of the acetal moiety. The utility of the reaction was demonstrated by the short and protective group-free syntheses of (L)-deoxyribonucleoside and –amicetose glycoside.terocyclic glycosides free of protecting and directing groups is reported.
