Conformational rearrangements by water-soluble peptoid foldamers.
Peptoids are a family of N-substituted glycine oligomers that are capable of forming stable helical structures. We seek peptoid monomers that can establish a strong folding propensity in aqueous conditions. Here we utilize L-phenylalanine tert-butyl ester as a readily available reagent for the synthesis of (S)-N-(1-carboxy-2-phenylethyl)glycine oligomers. The products form stable secondary structures in aqueous solution in which the conformation is dramatically responsive to variations in pH and solvent composition.
