Used as a key intermediate in the synthesis of antiviral medications, particularly in the production of nucleoside analogs. Its fluorinated tetrahydrofuran core enables enhanced metabolic stability and bioavailability in final drug compounds. Commonly employed in the development of experimental therapies targeting RNA viruses, where the benzoate ester groups assist in membrane permeability. Also utilized in stereoselective synthesis due to its defined chiral centers, allowing precise construction of complex pharmaceutical molecules.
