A recently developed efficient method for intramoleculardirectarylation is employed on a doubly functionalized calix[4]arene fixed in the cone conformation. The reaction takes place in high yield leading to meta substituted calix[4]arenes. The functionalities are located at two opposite aromatic rings and the two possible diastereomers are obtained in a 1:1 ratio. Full sets of data including crystal
