Abstract / Bemerkung
Peptidotriazolamers are hybrid foldamers combining features of peptides and triazolamers-repetitive peptidomimetic structures with triazoles replacing peptide bonds. We report on the synthesis of a new class of peptidomimetics, containing 1,5-disubstituted 1,2,3-triazoles in an alternating fashion with amide bonds and the analysis of their conformation in solid state and solution. Homo-or heterochiral peptidotriazolamers were obtained from enantiomerically pure propargylamines with stereogenic centers in the prop-argylic position and alpha-azido esters by ruthenium-catalyzed azide-alkyne cycloaddition (RuAAC) under microwave conditions in high yields. With such building blocks the peptidotriazolamers are readily available by solution phase synthesis. While the conformation of the homochiral peptidotriazolamer Boc-Ala[5Tz] Phe-Val[5Tz] Ala-Leu[5Tz] Val-OBzl resembles that of a beta VIa1 turn, the heterochiral peptidotriazolamer Boc- D-Ala[5Tz] Phe-D-Val[5Tz] Ala-d-Leu[5Tz] Val-OBzl adopts a polyproline-like repetitive structure.
