Synthesis of 4-Deoxy-L-(and D-)hexoses from Chiral Noncarbohydrate Building Blocks

4-Deoxy-L-hexoses were synthesized starting from our previously reported reagent 1 and (R)-benzyl glycidyl ether, which led in few steps to a substituted dihydropyran 6. The stereocontrolled hydroxylation of the latter afforded the corresponding 4-deoxy-L-hexoses 7a, 9, and 11. The same procedure, starting from (S)-benzyl glycidyl ether, enabled the preparation of their D-series enantiomers.
