Base-promoted rearrangement of sugar epoxides to unsaturated sugars

(Chemical Equation Presented) A simple and efficient method for rearranging 2,3-anhydro carbohydrates to unsaturated sugars has been developed. The exceptionally mild reaction conditions and high stereoselectivity should make this an attractive method for the preparation of unsaturated carbohydrate derivatives.

Regioselective monotosylation of non-protected and partially protected glycosides by the dibutyltin oxide method

Tosylation of non-protected glycopyranosides with p-toluenesulfonyl chloride in the presence of 4-dimethylaminopyridine, after activiation of the glycosides by dibutyltin oxide, gave mono-O-tosylates in good yield. The regioselectivity in this tosylation
