homologous anionic ortho-Fries rearrangement to give 7-16. The stereochemical outcome of the rearrangement is dependent on the reaction conditions and the conformation of the starting material. Stereochemical and structural proof has been secured by the X-ray crystal structure of calix[4]arene 10 having only one equatorial carboxamide moiety. The use of this novelclass of methylene bridge-functionalized
