Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and enzyme inhibitors. Its structure serves as a scaffold for compounds with biological activity, including those targeting neurological disorders. It is also employed in research related to peptidomimetics due to its ability to mimic proline-like conformations in peptides, enhancing metabolic stability and bioavailability. Additionally, it finds use in the preparation of chiral ligands for asymmetric synthesis in medicinal chemistry.
