Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its enantiomerically pure structure makes it valuable for creating selective serotonin reuptake inhibitors (SSRIs) and other neuroactive compounds. Commonly employed in asymmetric synthesis to introduce chirality in drug candidates. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its rigid cyclic framework and functional group compatibility.
