Used in pharmaceutical synthesis as a key chiral building block for the development of nicotinic acetylcholine receptor (nAChR) agonists and antagonists. Its rigid bicyclic structure and functional groups make it valuable in designing compounds targeting neurological disorders, including Alzheimer's and Parkinson's diseases. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic bioactive conformations of natural neurotransmitters. Also utilized in the preparation of enzyme inhibitors and receptor modulators where stereochemistry plays a critical role in biological activity.
