Fries Rearrangement in Calixarene Esters: A New Entry for the Synthesis of p-Substituted Calixarenes

Abstract
The Fries rearrangement was found to be a convenient method to synthesize p-acylcalixarenes from O-acylcalixarenes, the yields being relatively good (29–34%) as a synthetic method for p-substituted calixarenes.
