Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly those targeting the central nervous system. Its rigid bicyclic structure makes it valuable for designing ligands that interact with neurotransmitter receptors. Commonly employed in the development of potential therapeutics for neurological disorders such as depression, anxiety, and epilepsy. Also utilized in the preparation of novel analogs for structure-activity relationship studies due to its ability to mimic proline-like scaffolds in peptide-based drug design.
