Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and antiviral drugs. Its fluorinated tetrahydropyran structure enhances metabolic stability and bioavailability, making it valuable in optimizing drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid framework and stereochemical purity. Also utilized in the preparation of enzyme inhibitors where amine functionality allows for further derivatization.
