Derivatives of 1,6-dideoxy-1,6-epithio-β-D-glucopyranose have been shownto undergo oxidation reactions to afford the corresponding sulfoxides andsulfones. The sulfoxides participate in Pummerer reactions to afford thecorresponding α-acetoxy sulfides which were then oxidized further. Noneof the sulfoxides, sulfones or α-acetoxy sulfides prepared wereparticularly efficient glycosyl donors. Also presented
