Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active compounds. Its protected amine group (Boc) and reactive nitrile functionality allow selective reactions in multi-step organic syntheses. Commonly employed in the preparation of antidiabetic agents, such as DPP-4 inhibitors, due to the pyrrolidine scaffold’s role in mimicking peptide structures. The compound enables efficient chirality transfer and is valued in medicinal chemistry for building complex molecules with high stereochemical control.
