合成路线1
该中间体在本合成路线中的序号：(II)The reaction of the glucopyranosyl bromide (I) (or its chloride analogue) with the N-acyl-L-serine benzyl ester (II) by means of Ag-OTf in dichloroethane gives the glucoside (III), which is deprotected at the amino group with Zn and AcOH yielding the 2-aminoglucoside (IV). The condensation of (IV) with the tetradecanoic acid (V) by means of EDDQ in dichloromethane affords the amide (VI), which is finally deprotected by hydrogenation with H2 over PtO2 in THF/AcOH.
