Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its bromomethyl group allows for easy functionalization, making it valuable in coupling reactions to construct complex molecules. Commonly employed in the preparation of protease inhibitors and other bioactive compounds where the (R)-configuration is critical for biological activity. Also utilized in medicinal chemistry research for generating libraries of pyrrolidine-containing compounds for drug discovery.
