Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its naphthyl group enhances lipophilicity and binding affinity, making it valuable in drug design for improved target interaction. Commonly employed in asymmetric synthesis to introduce stereocenters in medicinal chemistry campaigns. Also utilized in the preparation of enzyme inhibitors and receptor ligands due to its structural rigidity and stereochemical purity.
