  Conformationally Constrained Aliphatic−Aromatic Amino-Acid-Conjugated Hybrid Foldamers with Periodic β-Turn Motifs

  摘要：

  In this note, we describe the design, synthesis, and structural studies of novel hybrid foldamers derived from Aib-Pro-Adb building blocks that display repeat beta-turn structure motif. The foldamer having a conformationally constrained aliphatic-aromatic amino acid conjugate adopts a well-defined, compact, three-dimensional structure, governed by a combined conformational restriction imposed by the individual amino acids with which it is made of. Conformational investigations by single-crystal X-ray and solution-state NMR studies were undertaken to investigate the conformational preference of these foldamers with a hetero-backbone. Our findings suggest that constrained aliphatic-aromatic amino acid conjugates would offer new avenues for the de novo design of hybrid foldamers with distinctive structural architectures.
