WebOct 20, 2024 · Peptoids, N-substituted glycine oligomers, are an important class of foldamers that can adopt polyproline-type helices (PP-I and PP-II), given that the majority of their sequence consists of chiral, bulky side chains. Herein a new approach for the stabilization of a pure PP-I-like peptoid helix through metal coordination is introduced.
