A) Bis‐ornithine octamer with wheel diagram showing the terminal δ‐residue lacking an H‐bond partner B) Heptamer 7 also with wheel diagram (lacking the labile terminal residue) with two of the α‐residues replaced by protected ornithines, which on deprotection gives diamine 8. C) Single crystal XRD (CCDC: 2252029) of the protected bis‐ornithine shows an H‐bond interaction between carbamates along with the same apolar interaction.
