Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents such as antipsychotics and antidepressants. Its rigid bicyclic structure makes it valuable in medicinal chemistry for mimicking bioactive conformations of neurotransmitters. Commonly employed in the preparation of selective enzyme inhibitors and receptor modulators due to its ability to enhance metabolic stability and binding affinity. Also utilized in the design of peptidomimetics where structural constraint improves oral bioavailability and target specificity.
