Used in peptide synthesis as a protected amino acid building block, particularly in the development of modified peptides with enhanced stability or specific biological activity. The Fmoc group allows for solid-phase synthesis under mild basic conditions, while the furyl side chain can participate in post-assembly modifications, such as photoclick reactions, enabling bioconjugation or cyclization strategies in drug design and chemical biology. Its D-beta-homoalanine backbone introduces structural constraints that may improve metabolic resistance or receptor selectivity in peptidomimetic compounds.
