Used in the synthesis of complex organic molecules, particularly in the pharmaceutical industry for the production of peptide-based drugs. It serves as a key intermediate in the preparation of proline derivatives, which are essential in designing protease inhibitors and other bioactive compounds. Its Boc-protected group ensures selective reactions during multi-step synthesis, while the benzyl ester facilitates controlled deprotection. This compound is also valuable in research for developing new therapeutic agents targeting diseases like cancer and viral infections.
