The synthesis of a novel Phe-Ala dipeptide mimic, built up on a diazaspirocyclic lactam core, is presented. This new scaffold was evaluated for conformational mimicry of reverse turn by combining molecular modeling, IR, NMR, and X-ray diffraction experiments. All these tools agree on the presence of a strong intramolecular hydrogen bond, thus demonstrating the ability of this spiro compound to act
提出了在二氮杂螺环内酰胺核心上构建的新型Phe-Ala二肽模拟物的合成。通过结合分子建模,IR,NMR和X射线衍射实验,评估了该新支架的反向构象构象。所有这些工具都同意存在强大的分子内氢键,从而证明该螺环化合物具有充当II'型β-转角诱导剂的能力。
