straightforward synthesis of C2-symmetric azole-containing macrocyclic peptides is presented. This type of macrocycle possesses four amide groups directed into the interior of the scaffold that act as hydrogen-bond donors and two nitrogen atoms from the azole unit that act as hydrogen-bond acceptors. This arrangement makes them sensitive receptors for Y-shaped anions like AcO– and H2PO4– with a selectivity for dihydrogen
