Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of neuroactive compounds and anticonvulsant drugs. Its structure supports the formation of gamma-aminobutyric acid (GABA) analogs, which modulate neurotransmission. Commonly employed in medicinal chemistry for building chiral, cyclic amino acid derivatives that enhance metabolic stability and blood-brain barrier penetration in drug candidates. Also utilized in the preparation of enzyme inhibitors and receptor ligands targeting central nervous system disorders.
