The introduction of chiral alkyl substituents into the lower rim of calix[4]arene immobilised in the <i>1,3-alternate</i> conformation led to a system possessing a preorganised ureido cavity hemmed with chiral alkyl units in the near proximity. As shown by the <sup>1</sup>H NMR titration experiments, these compounds can be used as receptors for chiral anions in DMSO-<i>d</i> <sub>6</sub>. The chiral recognition ability can be further strengthened by the introduction of another chiral moiety dire ...[more]
