Efficient Construction of Proline-Containing β-Turn Mimetic Cyclic Tetrapeptides via CuAAC Macrocyclization
摘要:
A range of macrocyclic beta-turn mimetic tetrapeptides was prepared by efficient copper-tris(triazole) ligand complex catalyzed azide-alkyne "click" macrocyclizations in good to high yields. Preliminary conformational studies using X-ray crystallography and NMR spectroscopy demonstrated the presence of intramolecular H-bonds characteristic of beta-turns in these cyclic tetrapeptides.
