ONE-POT SYNTHESIS OF 11,23-BIS(IMIDAZOL-1-YL)CALIX[4]ARENE DERIVATIVES BASED ON THE UPPER RIM OF BISAMINOCALIX[4]ARENE

摘要

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-bisaminocalix[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.
