By sequential synthesis the four 2,6-dideoxy saccharide moieties of the kijanimicin tetrasaccharide could be stereoselectively assembled. For formation of all required 2-deoxy α-glycoside linkages various S-(hexopyranosyl)-phosphorodithioates as donor structures could be convincingly employed. The terminal 2-deoxy β-glycoside linkage was stereoselectively formed following the dibromomethyl methyl ether

As deoxysugars are integral components of many natural products, the development of efficient chemical and enzymatic routes to prepare these compounds is of particular interest. Herein, we report a comparison of several synthetic methodologies used to prepare protected derivatives of the 2,6-dideoxysugar L-digitoxose. A novel, stereoselective synthetic route to efficiently access methyl 4-O-tert-butyldimethylsilyl-2,6-dideoxy-3-O-trimethylsilyl-alpha-L-ribo-hexopyranoside in 35% yield over nine facile steps is described.
