Schellman Motif in Dehydrooligopeptides: Crystal and Molecular Structure of Boc‐Val‐ΔPhe‐Leu‐Phe‐Ala‐ΔPhe‐Leu‐OMe

Abstract

Secondary structural motifs found in peptides are also generated in model compounds containing α,β‐didehydrophenylalanine residues (ΔPhe). A short peptide containing two ΔPhe units, Boc‐Val‐ΔPhe‐Leu‐Phe‐Ala‐ΔPhe‐Leu‐OMe, was found to assume a 310/α‐helical conformation terminated by a Schellman motif.
