Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of bioactive molecules and receptor ligands. Its rigid polycyclic structure makes it valuable in medicinal chemistry for designing compounds with specific stereochemistry and enhanced binding affinity. Commonly employed in the preparation of protease inhibitors and central nervous system agents due to its ability to mimic peptide motifs and stabilize molecular conformation. Also utilized in materials science for constructing chiral frameworks in asymmetric catalysis.
