Used primarily in the synthesis of pharmaceutical intermediates, this compound plays a key role in the development of antimuscarinic drugs. It is notably involved in the production of solifenacin, a medication used to treat overactive bladder by relaxing the muscles in the bladder. Its structure allows for effective binding and selectivity towards muscarinic receptors, making it valuable in urological therapeutics. Additionally, due to its bicyclic heterocyclic backbone, it serves as a building block in medicinal chemistry for designing new bioactive molecules with improved pharmacokinetic profiles.
