Used in the synthesis of nucleoside analogs, particularly in antiviral drug development. Serves as a key intermediate in constructing modified sugar moieties found in therapeutic agents targeting RNA and DNA viruses. Its protected functional groups allow selective deprotection and coupling in multi-step organic syntheses. Commonly employed in the preparation of prodrugs and phosphoramidite building blocks for oligonucleotide synthesis. Valuable in medicinal chemistry for enabling efficient and stereoselective glycosidic bond formation.
