Used primarily in peptide synthesis as a chiral building block, this compound enables the incorporation of a furan-containing amino acid derivative into peptide chains. The Fmoc group provides orthogonal protection, allowing selective deprotection under mild basic conditions while maintaining stability during solid-phase synthesis. Its (S)-configuration ensures stereochemical control, making it valuable in the preparation of bioactive peptides and peptidomimetics with defined secondary structures. The furan ring can serve as a site for further functionalization or as a structural mimic, useful in drug discovery and the development of enzyme inhibitors.
