Abstract

A calix[6]arene derivative where all methylene bridges have been formally replaced by two different types of groups (carbonyl and bromomethylene, 7), was prepared via bromination (NBS, CH₂Cl₂, irradiation) of a diketocalix[6]arene. Reaction of all-trans 7 with MeOH afforded the all-trans decamethoxy ether calix[6]arene derivative.
