Two new 18-membered tetralactams with two dimethyleneoxy moieties are synthesized by direct macrocyclization or steps reaction.In the latter case symmetrical or unsymmetrical compounds can be obtained.The unsymmetrical tetralactam shows a very high selectivity for barium vs.Na+ and Zn2+ and to a lesser extent vs.K+, Mg2+ and Ca2+ in the extraction procedure with picrates.In addition, the stability constants are determined for the two 1:1 tetralactam:Ba2+ complexes by UV spectrophotometry in THF solution.
