An expeditious approach to various protected hexoses has been developed by the use of the Sharpless catalytic asymmetric dihydroxylation reaction. Applying the Sharpless catalytic asymmetric dihydroxylation reaction on vinylfuran, diols with high enentioexcess are produced. The resulting diols can be stereoselectively transformed into either protected D- or L-mannose in five steps and approximately 39% yield from furfural. Similarly, both D- and L-talose and gulose have been synthesized in 19% overall yields, respectively. Using a modified strategy, both protected D- and L-gulo- and allo-sugar-δ-lactones were synthesized in eight steps and ~-20% overall yield from furfural. (C) 2000 Elsevier Science Ltd.

A flexible enantioselective synthesis of highly funcfionalized 5- substituted α,β-unsaturated δ-lactones has been achieved by applying the sharpless catalytic asymmetric dihydroxylation to vinylfuran as the key step. The resulting diols are produced in high enantio excess and can be stereoselectively transformed into differentially protected δ-lactones through a short reaction sequence.
