The insecticidal polyether antibiotic X-206 (1) complexes potassium ions using nearly all of its O-atoms either for binding to the metal ion or for participation in a H-bonding network which helps to hold X-206 in the ionophoric tertiary structure. The group OHC(22) is not involved in these processes. It was supposed that derivatization of this group would not affect the ionophoric properties and would
