A process for the preparation of a 4’-azido-2’,3’,5’-triacyl-nucleoside compound (I;B=B1; R1 is R1aCO-and R2 is R2aCO-) or a 4’-azidonucleoside compounds (I; B is B1 or B2 and R1 and R2 are hydrogen and acid addition salts thereof) wherein R1a and R2a are independently C1-10 alkyl or phenyl optionally substituted with 1 to 3 substituents selected from the group consisting of alkyl, alkoxy, halogen, nitro or cyano and R3 is selected from the group consisting of hydrogen, C1-6 alkyl, C1-3 haloalkyl and halogen, comprising contacting a 5’-iodo compound II with a peracid, R2aC(O)OOH, an acid R2aC(O)OH and a phase transfer catalyst and interconverting a uridine B1 to a cytosine B2. The present process provides the 4’-azidonucleosides safely and selectively in high purity with increased efficiency.
The invention provides unsaturated phosphonates of Formula I or a tautomer or pharmaceutically accepatble salt thereof, as described herein, as well as pharmaceutical compositions comprising the compounds, and therapeutic methods comprising administering the compounds. The compounds have anti-viral properties and are useful for treating viral infections (e.g. HCV) in animals (e.g. humans).
