Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of antiviral and antidiabetic agents. Its structure serves as a key intermediate for active ingredients that target enzyme inhibition, especially in protease and kinase inhibitors. Commonly employed in research and process chemistry for constructing complex molecules requiring stereochemical control. Also utilized in the preparation of cyclic peptides and peptidomimetics due to its rigid pyrrolidone framework.
