Used in pharmaceutical synthesis as a chiral building block for developing bioactive molecules, particularly in the production of protease inhibitors and antiviral agents. Its stereochemistry makes it valuable for constructing enantioselective intermediates in drug development. Commonly employed in the synthesis of glycine transporter inhibitors and other central nervous system-targeted therapeutics. Also utilized in the preparation of peptidomimetics due to its structural similarity to proline derivatives, enhancing metabolic stability and bioavailability in peptide-based drugs.
