Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its chiral cyclopentyl backbone with protected amine groups makes it valuable in the development of neurokinin antagonists and other receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its conformational rigidity and stereochemistry. Also utilized in the preparation of peptidomimetics and enzyme inhibitors where controlled amine functionality is required.
