Used as a building block in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its rigid bicyclic structure makes it valuable in the design of nitrogen-containing heterocycles, often employed in drug discovery for its ability to influence molecular conformation and binding affinity. Commonly utilized in the development of kinase inhibitors and receptor modulators. Also serves as a ligand in catalytic reactions, enhancing selectivity and efficiency in asymmetric synthesis.
