Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticonvulsant drugs. Its structural features allow for selective binding in biological systems, making it valuable in designing enzyme inhibitors. Commonly employed in the preparation of peptidomimetic compounds where metabolic stability and bioavailability are critical. Also utilized in research for creating novel neuroactive agents due to its ability to mimic natural amino acids while resisting degradation.
