Used as a key chiral intermediate in the synthesis of antiepileptic drugs, particularly in the production of brivaracetam. Its stereochemistry plays a critical role in enhancing the drug’s binding affinity to synaptic vesicle protein 2A (SV2A) in the brain. Also employed in the development of other central nervous system agents due to its ability to cross the blood-brain barrier effectively. Commonly utilized in asymmetric synthesis routes where enantiomeric purity is essential for pharmacological activity.
