Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders and metabolic diseases. Its protected azetidine structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex molecules with high stereochemical purity. Commonly employed in the preparation of protease inhibitors and receptor modulators where the three-membered ring system contributes to enhanced metabolic stability and binding affinity.
