Alkylation of azido sugar (XLIV) with 1-iododecane (LI) in the presence of Ag2O provided decyl ether (LII). Then, selective acetonide hydrolysis in (LII) to (LIII), followed by silylation with tert-butyldimethylsilyl chloride provided the bis-silyl ether (LIV). Alcohol (LIV) was then protected as the allyl carbonate (LV) by treatment with phosgene, followed by allyl alcohol. The primary silyl ether group of (LV) was selectively removed by treatment with HF giving the monosaccharide (LVI), which was coupled with imidate (XXXIV) yielding disaccharide (LVII).
