9/11 Mixed Helices in α<i>/</i>β Peptides Derived from C‐Linked Carbo‐β‐Amino Acid and <scp>L</scp>‐Ala Repeats

Abstract

A new twist: The α/β hybrid dipeptide repeats prepared from alternating C-linked carbo-β3-amino acid and L-Ala residues show a high propensity for mixed helices and produce hitherto unknown right-handed 11/9 and 9/11 helical structures (see picture).
