-Bn-Hydrazino/α] Trimers: Determination of the Δ<i>δ</i>
Value for the γ-Turn Structuration
The conformational behavior of 1:1 [α/α‐Nα‐Bn‐hydrazino] and 1:1 [α‐Nα‐Bn‐hydrazino/α] oligomeric (dimer and/or trimer) pseudopeptides in CDCl3 has been studied by 1H NMR and IR spectroscopy. This study has highlighted the self‐organization of the oligomers by an alternation of the γ‐turn and hydrazinoturn and allowed the Δδ value for the γ‐turn structuration to be calculated for the first time.
