Description

(S)-Fmoc-2-Amino-4,4-Difluoropentanoic Acid features a sterically hindered difluoromethyl group that enhances metabolic stability in peptide synthesis. The Fmoc protecting group enables efficient N-terminal coupling under standard conditions, while the chiral amino acid backbone supports high diastereoselectivity in chain elongation. This derivative serves as a key building block for fluorinated peptidomimetics and bioactive oligomers.

Application

(S)-Fmoc-2-Amino-4,4-difluoropentanoic acid serves as a valuable chiral building block for peptide synthesis and medicinal chemistry. The Fmoc group enables efficient solid-phase peptide coupling, while the 4,4-difluoropentanoic acid moiety imparts enhanced metabolic stability and modulates physicochemical properties. Its bench-stable nature and compatibility with standard coupling conditions facilitate reliable incorporation into complex scaffolds.
