PROCESS FOR PREPARING BRANCHED RIBONUCLEOSIDES FROM 1, 2-ANHYDRORIBOFURANOSE INTERMEDIATES

PROCESS FOR PREPARING BRANCHED RIBONUCLEOSIDES FROM 1, 2-ANHYDRORIBOFURANOSE INTERMEDIATES

A process is provided for the preparation of branched-chain ribonucleosides of formula (I): from the 1,2-anhydroderivatives of formula (II). wherein PG is a hydroxyl protecting group, B is a purine or pyrimidine nucleobase, and R1 is C1-6 alkyl. The compounds of formula (I) are inhibitors of HCV pol...

Zusammenfassung:A process is provided for the preparation of branched-chain ribonucleosides of formula (I): from the 1,2-anhydroderivatives of formula (II). wherein PG is a hydroxyl protecting group, B is a purine or pyrimidine nucleobase, and R1 is C1-6 alkyl. The compounds of formula (I) are inhibitors of HCV polymerase useful in the treatment of HCV infection.
