合成路线1
该中间体在本合成路线中的序号：(XXXIV)Monosaccharide (XXI) was activated as the trichloroacetimidate (XXXIV) upon treatment with trichloracetonitrile. Coupling between the protected monosaccharide (XXXIII) and imidate (XXXIV) using silver triflate as the coupling promoter produced the protected disaccharide adduct (XXXV). After reductive cleavage of the trichloroethyl carbamate protecting group of (XXXV), the resultant amine (XXXVI) was acylated with vaccenoyl chloride (XXXVII) giving amide (XXXVIII).

该中间体在本合成路线中的序号：(XXXIV)Azido sugar (XLVIII) was reduced to the corresponding amine (XLIX) employing the in situ generated tin tris(benzenthiolate) triethylamine complex. Amine (XLIX) was then protected as the trichloethyl carbamate (L) by treatment with Troc-chloride and pyridine. After desilylation of (L) with HF, the resultant alcohol was activated as the trichloroacetimidate (XXXIV) as in Scheme 27814501e.

合成路线3
该中间体在本合成路线中的序号：(XXXIV)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).
