Abstract: | We have previously reported the synthesis of enantiopure β,γ‐diamino acids and relevant short α/γ‐peptide containing such building blocks. Complete nuclear magnetic resonance (NMR) studies, together with molecular modeling, highlighted the ability of a β,γ‐diamino acid to induce various intramolecular turns. In this paper, we describe for the first time the formation of a dimeric structure constituted by α/γ/α‐tripeptide and stabilized by intermolecular interactions. A structural model is proposed based on extensive NMR measurements. |
