The title oxacalix[3]arene macrocycles 1 have been synthesized in yields of 12-32% by an acid-catalyzed, high-dilution condensation of 2,6-bis(hydroxymethyl)-p-subtituted-phenols, where R = t-Bu, i-Pr, Et, Me, and Cl. The macrocycles are isolated in high purity without chromatography, as the sodium or potassium,salts of their monoanions. Metal-binding studies indicate that, Like the related calixarenes, the oxacalix[3]arenes bind alkali metals only in the presence of base (Na(+)approximate to K+ > Li+).
