Abstract A convenient and efficientsynthesis of 1,6-anhydro-2,4-dideoxy-β-D-threo-hexopyranose (2,4-dideoxy-levoglucosan) from levoglucosan has been developed. The method uses cheap reagents and requires only crystallization and distillation for preparation of pure product on a multigram scale. [Supplementary materials are available for this article.

Alkylation of (1R,2R,5R) -2-benzenesulfonyl-6,8-dioxa-bicyclo[3.2.1]octan-3-one, which is accessible from levoglucosan, afforded (1R,2R,5R)-2-benzenesylfonyl-2,4,4-trimethyl-6,8-dioxabicyclo[3.2.1]octan-3-one. This was further converted into (1S,2R,3S,5R)-2,4,4-trimethyl-6,8-dioxabicyclo[3.2.1]octan-3-ol representing the C9-C13 fragment of acutiphycin molecule.
