(αR)-α-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]-1,3-benzodioxole-5-propanoic acid is a chiral compound featuring an Fmoc-protected amino group and a benzodioxole moiety attached to a propanoic acid backbone. The Fmoc group is commonly used in solid-phase peptide synthesis to protect amino groups during chain assembly. The benzodioxole ring adds rigidity and aromaticity, which can influence the overall conformation and interaction of the molecule in biological systems. This compound is potentially useful in peptide synthesis or as a building block in the design of biologically active molecules.
