该中间体在本合成路线中的序号：(III)The protected glucuronic acid derivative (I) is hydrolyzed under alkaline conditions to furnish (II). The alcoholic hydroxyl groups of (II) are subsequently protected as the silyl ether (III) employing t-butyldimethylsilyl triflate in the presence of DMAP. The carboxyl group of (III) is further converted to the corresponding benzyl ester (IV) by DCC-mediated coupling with benzyl alcohol. Acylation of amine (IV) with phosgene leads to the carbamyl chloride (V). (1,2)
