(+) Levoglucosenone, a previously unavailable (+) enantiomer of 1,6-anhydro-3,4-dideoxy-β-D-glycero-hex-3-enopyranos-2-ulose, and its 5-hydroxymethyl analog have been synthesized in six steps in 28% and 41% overall yields from the known precursor, 5-hydroxymethyl-1,6-anhydro-α-L-altro-hexopyranose 1.

(+)-levoglucosenone - 5-hydroxymethyl-(+)-levoglucosenone - reductive decarboxylation - hydrous zirconium oxide - PDC oxidation
