Used in pharmaceutical synthesis as a chiral building block for developing neuroactive compounds. Its rigid polycyclic structure and multiple stereocenters make it valuable in the design of enzyme inhibitors and receptor ligands, particularly in central nervous system research. Commonly employed in the preparation of proline analogs and peptidomimetics to enhance metabolic stability and bioavailability in drug candidates. Also utilized in asymmetric synthesis to induce stereocontrol in complex molecule assembly.
