A new class of chiral macrocyclic polyethers containing 1,1’-biazulene unit was prepared from the reaction of 2,2’-dihydroxy-3,3’-bis(methoxycarbonyl)-1,1’-biazulene with tetra- or pentaethyleneglycol ditosylate by a high dilution technique. Complexation study with alkali metals by 1H nmr indicated ion selectivity for these macrocycles. The crystal structure was studied by X-ray diffraction.
