Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where protected pyrrolidine scaffolds are required. Its structure allows for selective functionalization in multi-step organic syntheses, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of protease inhibitors and other bioactive agents due to the stability and compatibility of the tert-butyl carbamate (Boc) protecting group under various reaction conditions.
