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 fluoromethyl phenyl sulfone (B) by means of diethyl chlorophosphate and lithium hexamethyldisylazide in THF affords the fluorovinyl sulfone (V) as a mixture of (E) and (Z) isomers that is separated by flash chromatography. The (Z)-isomer (V) is treated with tributyl tin hydride and AIBN in refluxing benzene to give the fluorovinyl stannane (VI), which is finally treated with KF in refluxing methanol to afford the target compound.

The acetylation of uridine (I) with acetic anhydride gives the 2',3',5'-triacetyl derivative (II), which is treated with SOCl2 and sodium ethoxide yielding the 4-ethoxypyrimidinone (III). The partial protection of (III) with 1,3-dichloro-1,1,3,3-tetraisopropyldisiloxane (IV) yields the silylated compound (V), which is oxidized with oxalyl chloride to the silylated furanone (VI). The reaction of (VI) with fluoromethyl phenyl sulfone (A) by means of diethyl chlorophosphate (B) and lithium hexamethyldisylazide in THF affords the fluorovinyl sulfone (VII) as a mixture of (E) and (Z) isomers that is separated by flash chromatography. The (Z)-isomer (VII) is treated with tributyl tin hydride and AIBN in refluxing benzene to give the fluorovinyl stannane (VIII), which is finally treated with CsF and NH3 in refluxing methanol to afford the target compound.

A new synthesis of tezacitabine has been described: Protection of cytidine (I) with 1,3-dichloro-1,1,3,3-tetraisopropyldisiloxane (II) in pyridine gives the protected cytidine (III), which is oxidized with trifluoroacetic anhydride (TFAA)/DMSO in THF and treated with TEA to yield the 2'-deoxy-2'-oxocytidine derivative (IV).

N-Boc-Homophenylalanine (I) was coupled to N,O-dimethyl hydroxylamine using DCC, and the resulting N-methoxy amide (II) was reduced to aldehyde (III) with LiAlH4. Sulfonyl phosphonate (VI), (prepared from methyl phenyl sulfone (IV) and diethyl chlorophosphate (V)), was then condensed with aldehyde (III) in the presence of NaH to provide the vinylogous sulfone (VII). Subsequent acid deprotection of the Boc group of (VII) yielded amine (VIII). This was finally coupled with mixed anhydride (X), (obtained from morpholinocarbonyl-phenylalanine (IX) and isobutyl chloroformate in the presence of N-methylmorpholine), to furnish the target amide.

Rearrangement of 5-bromo-2-methylpyridine 1-oxide (LXVII) with trifluoroacetic anhydride gives (5-bromopyridin-2-yl)methyl trifluoroacetate (LXVIII), which, without isolation, is hydrolyzed in MeOH solution, yielding (5-bromopyridin-2-yl)methanol trifluoroacetate salt (LXIX). Basification of compound (LXIX) with K2CO3 followed by chlorination with SOCl2 affords 5-bromo-2-(chloromethyl)pyridine (LXX), which is subsequently condensed with diethyl phosphite in the presence of LiHMDS, affording phosphonate (LXXI). Finally, Suzuki coupling of bromopyridine derivative (LXXI) with 3-fluorophenylboronic acid (V) by means of Na2CO3 and Pd/C in H2O at 75 °C provides the phenylpyridine compound (XII) .
O-Protection of 6-methyl-3-pyridinol (LXXII) with TIPSCl in DMF gives the corresponding silyl ether (LXXIII), which is then condensed with diethyl chlorophosphate (LXXIV) in the presence of BuLi and DIEA in THF, yielding diethyl phosphonate (II) .
