A straightforward synthesis of C3-symmet:ric, imidazole-containing, macrocyclic peptides with different binding arms is presented, The chirality of the backbone and the selection of adequate receptor arms make these systems highly selective receptors for α-chiral primary organoammonium ions. Furthermore, the receptors have the ability to discriminate between enantiomeric guests with selectivity ratios of up to 87:13, The binding constants and the selectivity ratios were estimated by standard 1H NMR titration techniques in CDCl3.
