合成路线1
该中间体在本合成路线中的序号：(IX)The protection of cytidine (I) with 1,3-dichloro-1,1,3,3-tetraisopropyldisiloxane (II) and dimethylformamide dimethylacetal (A) in pyridine gives the fully protected cytidine (III), which is oxidized with oxalyl chloride in DMSO/dichloromethane yielding the 2'-deoxy-2'-oxo derivative (IV). The reaction of (IV) with labeled fluoromethyl phenyl sulfone (V) by means of diethyl chlorophosphate (B) and lithium hexamethyldisylazide in THF affords the fluorovinyl sulfone (VI) as a mixture of (E) and (Z) isomers that is separated by flash chromatography. The (Z)-isomer (VI) is treated with tributyl tin hydride and AIBN in refluxing benzene to give the fluorovinyl stannane (VII), which is finally treated with KF in refluxing methanol to afford the labeled target compound.
