Used in organic synthesis, particularly in the preparation of chiral ligands and auxiliaries for asymmetric reactions. It serves as a building block in the development of peptidomimetics and pharmaceutical intermediates due to its stereochemical stability and compatibility with solid-phase peptide synthesis. The Fmoc group allows for mild deprotection conditions, making it ideal for stepwise synthesis in complex molecule assembly. Also employed in the design of foldamers and functional materials where control over molecular conformation is essential.
