Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with potential neurological or cardiovascular effects. Its bicyclic structure and functional groups make it valuable for constructing complex heterocyclic systems in medicinal chemistry. Commonly employed in the preparation of protease inhibitors and receptor modulators due to its ability to mimic peptide bonds and enhance metabolic stability. Also utilized in solid-phase synthesis and combinatorial chemistry for drug discovery.
