An efficient synthesis of a structurally congested tetrasaccharide portion from the cellulosome produced byClostridium thermocellumhas been accomplished through a stepwise glycosylation strategy. The key steps for the synthesis include the stereocontrolled construction of a range of challenging 1,2‐cisglycosidic linkages. The 5‐O‐(2‐quinolinecarbonyl) substituted D‐galactofuranosyl thioglycoside2, 4,6‐O‐benzylidene protected 2‐azido‐2‐deoxyglucose thioglycoside3 c, and 4,6‐O‐benzylidene protected D‐galactopyranosyl thioglycoside4were employed as glycosyl donors, respectively, for the high‐yielding and stereoselective formation of the corresponding 1,2‐cis‐α‐Galf, α‐GlcNAc, and α‐Galplinkages.
