ResumoFourfold homologous anionic ortho-Fries rearrangement in the twofold bridged tetra-O-carbamate 3 gave the tetrakis(carboxamidomethyl)resorc[4]arene 4 in 68% yield. Compound 3 was prepared by selective carbamoylation of methylresorc[4]arene 1, followed by the bridging of the remaining OH groups in tetra-O-carbamate 2.Key words: resorc[4]arenes, selective functionalizations, homologous anionic ortho-Fries rearrangement.
