Aza-1,2,3-triazole-3-alanine Synthesis via Copper-Catalyzed 1,3-Dipolar Cycloaddition on Aza-progargylglycine
摘要:
The parallel synthesis of seven aza-1,2,3-triazole-3-alanine azapeptides of the Growth Hormone Releasing Peptide-6 (GHRP-6) was accomplished via a Cu-catalyzed azide-alkyne [3+2] cycloaddition on an aza-propargylglycine residue anchored on Rink amide resin. Circular dichroism spectroscopy in water demonstrated that azapeptides which possess an aza-1,2,3-triazole-3-alanine residue at the Trp(4) position of the GHRP-6 sequence adopt beta-turn conformations.
