Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of neuroactive agents. Its rigid bicyclic structure and functional groups make it valuable for designing molecules that interact with central nervous system receptors. Commonly employed in the preparation of potent and selective ligands for neurological targets, including those involved in pain management and psychiatric disorders. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical specificity and ability to mimic peptide motifs.
