Used in the synthesis of peptidomimetic compounds and pharmaceutical intermediates, particularly in the development of enzyme inhibitors. Its naphthyl group provides a bulky aromatic moiety that enhances binding selectivity in receptor-targeted drugs. Commonly employed in asymmetric synthesis and chiral building block construction for bioactive molecules. Also utilized in medicinal chemistry for designing protease inhibitors and neuroactive agents due to its structural rigidity and stereochemical purity.
