  Conformationally Stable and Constrained Macrocarbocyclic Pseudopeptide Mimics ofβ-Hairpin Structures

  摘要：

  Subjecting a D-PrO-L-PrO template harboring N- and C-terminal omega-alkenyl amino acids to a ring-closure metathesis reaction afforded the corresponding macrocyclic alkenes. A cis-alkene analogue crystallized with one molecule each of water and chloroform, which were retained even after heating at 100degreesC. By using the reduced macrocyclic product as a template, the metathesis could be repeated twice on newly installed omega-alkenyl amino acids to give three-tiered macrocarbocyclic pseudopeptides as mixtures of conformers. NMR studies revealed the high conformational stability of these motifs.
