Used as a key intermediate in the synthesis of antiviral drugs, particularly in the production of nucleoside analogs. Its structure allows for selective modification in prodrug development, enhancing bioavailability and cellular uptake. Commonly employed in the manufacture of hepatitis C and HIV therapeutics due to its ability to mimic natural nucleosides, interfering with viral replication. The silyl and acetate protecting groups facilitate controlled reactivity during multi-step synthesis, making it valuable in pharmaceutical research and development.
