To obtain general rules of peptide design using alpha, beta-dehydro-residues, a sequence with two consecutive delta Phe-residues, Boc-L-Val-delta Phe-delta Phe-L-Ala-OCH3, was synthesized by azlactone method in solution phase. The peptide was crystallized form its solution in an acetone/water mixtur
