合成路线1
该中间体在本合成路线中的序号：(VII)Tetrazole-catalyzed phosphitylation of the tyrosinamide derivative (V) with O-2-(pivaloylthio)ethyl-N,N,N',N'-tetraisopropylphosphorodiamidite (VI) yields phosphoramidite (VII). This is subsequently coupled to azidothimidine (VIII) to furnish phosphite (IX), which is then oxidized to the corresponding phosphate (X) with t-butyl hydroperoxide. The N-Boc protecting groups of (X) are finally removed under acidic conditions to provide the title compound.
