Abstract

In our continuing studies concerning the versatility of the acid-catalyzed conversion of cinnamates to calix[4]resorcinarenes, we have demonstrated that 2,6-dimethoxycinnamic acid ethyl ester 3 undergoes an interesting rearrangement to afford the same calix[4]resorcinarenes as those obtained from the 2,4-dimethoxy isomer 1. The experimental results were substantiated by molecular mechanics calculations.
