Abstract

A simple one-pot synthesis for a new 11,23-bis(imidazol-1-yl)calix[4]arene derivatives in their cone conformation was reported by the four component condensation reaction of 11,23-bis-aminocalix[4]arene, aldehyde, benzil and ammonium acetate. This work provides a simple, efficient method for the construction of 11,23-bis(imidazol-1-yl)calix[4]arene derivatives on which the substituted imidazole rings are directly linked to their upper rim.
