合成路线1
该中间体在本合成路线中的序号：(XII)The intermediate, the glucopyranosyl bromide (I) has been obtained as follows: The reaction of 2-(trimethylsilylethyl)-2-amino-2-deoxy-4,6-O-isopropylidene-beta-D-glucopyranoside (VII) with Troc-Cl and NaHCO3 gives the N-protected glucoside (VIII), which is acylated with the tetradecanoic acid (IX) by means of EDC and 4-(1-pyrrolidinyl)pyridine in dichloromethane to yield the 3-O-acylated glucoside (X). The hydrolysis of the isopropylidene group of (X) with AcOH affords the diol (XI), which is selectively protected at the primary OH group with 2,2,2-trichloro-1,1-dimethylethyl chloroformate (XII) in pyridine to provide (XIII). The phosphorylation of the remaining OH group of (XIII) with diphenyl chlorophosphate (XIV) by means of DIEA in dichloromethane gives the phosphoric ester (XV), which is finally desilylated and hydrolyzed with TFA in dichloromethane, and treated with oxalyl bromide in dichloromethane/DMF to furnish the target glucopyranosyl bromide (I).

该中间体在本合成路线中的序号：(C)N-Protection of amino alcohol (VI) under Schotten-Baumann conditions with 2,2,2-trichloroethyl chloroformate (B) aforded carbamate (VII). Subsequent esterification of (VII) with acid (II) provided (VIII), which was followed by acetonide hydrolysis to give diol (IX). Selective protection of the primary hydroxyl of (IX) with 1,1-dimethyl-2,2,2-trichloroethyl chloroformate (C) furnished carbonate (X). Further phosphorylation of the free secondary hydroxyl of (X) with diphenylphosphoryl chloride (D) produced phosphate ester (XI). Conversion of the trimethylsily-ethyl glycoside (XI) into the desired glycosyl chloride (XII) was then accomplished by treatment with alpha,alpha-dichloromethyl methyl ether and ZnCl2.
