## Abstract The crystal and molecular structure of the pentapeptide Boc‐D‐Ala‐ΔPhe‐Gly‐ΔPhe‐D‐Ala‐OMe, containing two dehydrophenylalanine residues, was determined by x‐ray diffraction. The molecule crystallizes in the orthorombic P2~1~2~1~2~1~ space group, with __a__ = 10.439(3), __b__ = 15.319(3)
