Nonpeptidic Foldamers from Amino Acids: Synthesis and Characterization of 1,3-Substituted Triazole Oligomers

Abstract

Nonpeptidic foldamers capable of displaying protein-like functionality were prepared by swapping amide bonds with 1,2,3-triazole rings. The overall conformation of these triazole oligomers is largely dictated by dipole−dipole interactions between adjacent rings. Solution NMR studies suggest that a zigzag conformation, which closely mimics the β-strand structure, predominates in two different tetramers.
