Used in organic synthesis as a chiral building block for the preparation of nucleoside analogs, particularly in the development of antiviral agents. Its functionalized tetrahydrofuran core with defined stereochemistry allows for selective coupling reactions, making it valuable in medicinal chemistry for constructing biologically active molecules. The benzoate protecting groups enable controlled deprotection and further derivatization, while the allyl group offers a site for cross-coupling or functional modification. Commonly employed in research settings for designing modified sugars and nucleotides.
