Used primarily in pharmaceutical research as a chiral building block for the synthesis of neuroactive compounds. It serves as a key intermediate in the development of nicotinic acetylcholine receptor (nAChR) modulators, which are investigated for treating neurological disorders such as Alzheimer's disease, Parkinson's disease, and depression. Its structural similarity to nicotine allows selective interaction with receptor subtypes, making it valuable in structure-activity relationship (SAR) studies. Also employed in asymmetric synthesis due to its chiral pyrrolidine core, supporting the preparation of enantiomerically pure drugs.
