Used in organic synthesis as a chiral building block for pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its rigid, fused bicyclic structure with defined stereochemistry makes it valuable for designing enzyme inhibitors and receptor ligands. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in central nervous system (CNS)-targeted therapies. Also utilized as an intermediate in the preparation of peptidomimetics due to its ability to mimic peptide turn structures.
