Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its rigid bicyclic structure and defined stereochemistry make it valuable for designing bioactive molecules with high selectivity. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in optimizing receptor binding and metabolic stability. Also utilized in asymmetric synthesis as a scaffold or auxiliary due to its amine functionality, which can be readily modified for coupling reactions.
