合成路线1
该中间体在本合成路线中的序号：(XV)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).
