该中间体在本合成路线中的序号：(XV)Application of the sulfoxide glycosylation method to a mixture of disaccharide (XIII) and trisaccharide (XIV) generated the pentasaccharide core (XV). After cleavage of the trimethylsilyl ether of (XV) with HF.Pyr, methylation with iodomethane and NaH produced methyl ether (XVI). Installation of a further methoxy group in the alpha-position of the sulfide was achieved by oxidation with mercuric trifluoroacetate in the presence of MeOH, yielding (XVII). Desulfurization and simultaneous reduction of all azido groups of (XVII) by hydrogenation over PtO-2 furnished (XVIII).
