[3, 3]-Sigmatropic Rearrangement as a Powerful Synthetic Tool on Skeletal Modification of Unsaturated Sugars
TL;DR: In this article, a review on carbon-carbon and carbon-heteroatom bond formation as a skeleton modification on monosaccharides, through [3, 3]-sigmatropic rearrangement reactions on unsaturated sugar synthons, the generality of the reaction conditions and synthetic utilization of the resulting functionalized sugar building blocks is provided.

Studies on unsaturated sugars with particular reference to the synthesis of 6-Deoxy-6-fluoro derivatives
TL;DR: Three fluoro-substituted unsaturated sugars have been synthesized by transformations within the D-glucal and ethyl 2,3-dideoxy-α-D-erythro-hex-2-enopyranoside series.

A Rapid Route to Hex-1-enopyran-3-uloses
TL;DR: In this article, it was shown that triacetyl glucal can be converted to 6-O-triphenylmethyl ether or 6 O-benzoyl ester to promote solubility in chloroform, and the derivatives are oxidized in that solvent in 12 h or less.
