Used in organic synthesis as a chiral building block for the preparation of pharmaceuticals and bioactive compounds. It serves as a key intermediate in the synthesis of peptides and peptidomimetics, enabling the introduction of proline derivatives into complex molecules. Its chiral nature makes it valuable in asymmetric synthesis, particularly in the development of enantioselective catalysts and ligands. Additionally, it is employed in the study of enzyme mechanisms and protein folding due to its ability to mimic natural amino acids.
