Figure 3.

A) Crystal structure of foldamer 2 showing an unusual 13/11‐helix, where two packing conformations exist in the unit cell (CCDC: 2252028—see Supporting Information for ellipsoid plots)—differing only in the terminal δ‐residue which adopts either B) (a,a) or C) (e,e)‐conformations. D) Surface plot showing the ethyl‐group of one δ‐residue pointing towards the cyclohexyl unit of the (i+2) δ‐system. E) Wheel diagram representation of the octamer showing the interior α‐residues and the exterior facing δ‐residues, along with the terminal residue that lacks an H‐bond partner.
