title: Synthesis of diazacalix[8]arene and triazacalix[12]arene methyl ethers via intramolecular aryl amination.
abstract: Azacalixarenes derived from p-tert-butylphenol are generated by an intramolecular aryl amination strategy as the ring-closing step. The reaction produces the first examples of larger p-tert-butylcalixarenes with regioselective substitution of bridging methylenes with nitrogen atoms.
