合成路线1
该中间体在本合成路线中的序号:(XLII)Keto ester (XLI) was obtained by Reformatskii condensation of the organozinc reagent generated from benzyl bromoacetate (XL) with n-undecyl cyanide (XXXIX). Subsequent hydrogenolysis of the benzyl ester of (XLI) in the presence of Pearlman's catalyst furnished keto acid (XLII). Acylation of the diamino compound (XXXVIII) with ketoacid (XLII), by means of DCC, provided diamide (XLIII). Then, desilylation of (XLIII) to afford alcohol (XLIV) was accomplished employing HF in acetonitrile.

合成路线2
该中间体在本合成路线中的序号:(XXXI)The other monosaccharide building block (XXXIII) was also synthesized from the common intermediate (XII). Alkylation of (XII) with mesylate (XXIII), prepared from 1-decanol (XXII), gave the decyl ether (XXIV). After acidic acetonide hydrolysis of (XXIV) to yield (XXV), removal of the trifluoroacetamide by means of potassium tert-butoxide, with concomitant O-allyl group isomerization, furnished (XXVI). Imine (XXVII) was then obtained by exchange reaction of amine (XXVI) with benzophenone imine at 45 C. After silylation of the primary hydroxyl of (XXVII) with tert-butyldimethylsilyl chloride affording(XXVIII), the secondary hydroxyl group was protected as the allyl carbonate (XXIX) by sequential treatment with phosgene and then with allyl alcohol. Imine (XXIX) hydrolysis, followed by coupling of the resultant amine (XXX) with 3-oxotetradecanoic acid (XXXI) led to keto amide (XXXII). Precursor (XXXIII) was then obtained by desilylation of (XXXII) with HF.
