(Figure Presented) Thermodynamically driven epimerization at the trindane benzylic positions of "hexacarboxytrindanes" generates benzene rings with D3 symmetry and with R or S homotopic faces. Almost total resolution towards S trindanes was achieved by epimerization and transesterification with lithium (-)-mentholate. These structures are attractive cores for the construction of macromolecules in which asymmetry is induced by the center of the molecule. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
