Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of neuroactive compounds and enzyme inhibitors. Its rigid bicyclic structure and well-defined stereochemistry make it valuable for designing drugs targeting central nervous system disorders. The tert-butyl ester group allows for selective protection during multi-step syntheses, enabling controlled functionalization of the molecule. It is especially useful in the preparation of glutamate receptor modulators and other bioactive molecules where stereochemical precision is critical.
