Abstract

A novel, flexible synthesis of hemispherands {2,5,8-trioxa[9](3,3″) m-terphenylophanes 5a-d} with different central aromatic groups is described. The key step comprises the introduction of the central aromatic ring in the last step of the synthesis via a Suzuki cross-coupling reaction using palladium tetrakis(triplienylphosphine) as a catalyst and sodium or potassium cations serving as a template ion in the macrocyclization.
