Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its rigid bicyclic structure enhances metabolic stability and bioavailability in drug candidates. Commonly employed in the preparation of gamma-aminobutyric acid (GABA) analogs and other neuroactive compounds. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic peptide bonds while resisting enzymatic degradation.
