Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and peptide mimetics. Its functional groups allow for selective modifications in multi-step organic syntheses, making it valuable in medicinal chemistry for constructing complex ring systems. Commonly employed in the preparation of protease inhibitors and receptor modulators due to its structural rigidity and compatibility with solid-phase peptide synthesis. Also utilized in the creation of novel drug candidates targeting central nervous system disorders and metabolic diseases.
