Used primarily as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a key intermediate in the production of drugs targeting neurological disorders such as depression, cognitive impairment, and neuropathic pain. Its structural similarity to nicotine allows it to interact selectively with neuronal receptors, making it valuable in medicinal chemistry for designing selective agonists or antagonists. Also employed in asymmetric synthesis due to its chiral pyrrolidine core, facilitating the creation of enantiomerically pure compounds.
