Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and antifungal agents. Its structure allows for chiral synthesis, making it valuable in creating enantiomerically pure drugs. Commonly employed in the development of protease inhibitors and other bioactive molecules where a tetrahydrofuran ring enhances metabolic stability and binding affinity. Also utilized in research settings for building complex organic molecules due to its functional group compatibility and ring flexibility.
