Regio- and stereoselective iodinations under controlled Garegg conditions were performed on vicinal diols and contiguous triols located on pyranose templates. β-D-Fructo- orpsicopyranose-based diols were selectively iodinated at C-5 or C-4, respectively,

A regio- and stereoselective iodination has been performed on vicinal diols located on ketopyranose templates using the controlled- Garegg conditions. 3-O-Benzyl-1,2-O-isopropylidene-β-d-fructo- or psicopyranoses (1 or 4) were selectively iodinated, respectively, at C-5 or C-4 of the ketoses to afford the l-sorbo or d-sorbo iodohydrins.

A series of chiral ketones derived from carbohydrates were investigated as catalysts for the asymmetric epoxidation. Fructose-derived ketones are found to be efficient catalysts. The studies show that the structural requirements for the ketone catalysts are very stringent and different types of olefins may require ketones with different structural arrangements. The current study allows us to further understand the chiral ketone catalyzed asymmetric epoxidation and provides some insight for the development of new catalysts.
