An integrated enantio and diastereocontrolled route to both enantiomers of the eight possible hexoses has been explored starting from furfural, by employing the Sharpless asymmetric dihydroxylation as a key step. At the present, a route to six of the eight possible hexoses has been established. The present synthesis may be taken as a reversion of the sugar-originated furfural to the sugars via a levoglucosenone, a pyrolysate of cellulose, type intermediate.
