Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of enzyme inhibitors and central nervous system agents. Its rigid bicyclic structure makes it valuable for designing molecules with specific stereochemistry and enhanced metabolic stability. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic peptide bonds or serve as a scaffold in constrained analogs. Also utilized in the preparation of novel heterocyclic compounds for drug discovery programs targeting neurological disorders and inflammation.
