Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly pharmaceuticals. Its structure allows for selective functionalization, making it valuable in the development of drugs targeting central nervous system disorders and metabolic diseases. Commonly employed in medicinal chemistry for constructing enantiomerically pure piperazine-based molecules, which are found in several therapeutic agents including antipsychotics, antidepressants, and antidiabetic drugs. Also utilized in the preparation of protease inhibitors and receptor agonists/antagonists due to its favorable stereochemistry and compatibility with peptide-like frameworks.
