Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and bioactive molecules. Its fluorinated structure enhances metabolic stability and binding affinity, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in asymmetric synthesis to introduce stereochemical control in the preparation of complex organic molecules. Also utilized in the design of peptidomimetics due to its structural similarity to proline, enabling modulation of peptide conformation and stability.
