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.

1,1'-Methylenebisdiazoles Az1-CH2-Az2, Az1 and Az2 being two different diazoles, can be prepared selectively in three steps, through 1-hydroxymethyl- and 1-chloromethyldiazoles, by solid-liquid (S-L) phase transfer catalysis.
