Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and antiviral agents. Its structure supports the construction of complex molecules where a protected cyanopyrrolidine moiety is required. Commonly employed in medicinal chemistry for building chiral frameworks in drug candidates. Also utilized in the preparation of enzyme inhibitors due to the reactivity of the nitrile group and the stability provided by the benzyl carbamate protecting group.
