Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of enzyme inhibitors and receptor modulators. Its rigid polycyclic structure makes it valuable for designing molecules with high selectivity and binding affinity. Commonly applied in medicinal chemistry for optimizing drug candidates targeting neurological and inflammatory conditions. Also utilized in the preparation of peptidomimetics due to its ability to mimic peptide conformations, enhancing metabolic stability and oral bioavailability in drug design.
