Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the production of anticholinergic drugs. It serves as an intermediate in the preparation of active ingredients found in treatments for neurological and psychiatric disorders. Its rigid bicyclic structure and stereochemistry make it valuable for designing drugs with high selectivity and potency. Commonly employed in the development of muscarinic receptor antagonists, including medications for Alzheimer's disease, schizophrenia, and overactive bladder. Also utilized in the synthesis of certain antiviral and anti-Parkinson agents due to its ability to cross the blood-brain barrier effectively.
