Abstract
An efficient and versatile synthetic route to calixhydroquinones is describ ed. These macrocycles are activated towards meta substitution, and reaction with bromine gives the first examples of persubstituted, phenol-derived ca lixarenes. The effect of meta substitution on calixarene mobility is demons trated by the fixation of an otherwise mobile calix[4] system in the partia l cone conformer, and the slowing of the ring inversion rate in calix[8]are nes.
