Abstract
A series of highly preorganized molecular clefts were prepared from th e condensation of a -2,7-bis(1,1-dimethylethyl)-9,9-dimethylxanthene-5 acid with aromatic dianhydrides. The clefts are locked in a convergen t C-shape by restricted rotation about two C-(aryl)-N-(imide) bonds. T he synthesis and derivatization are reported. In addition, structural information is presented including the X-ray structure of the S-isomer of naphthalene diacid 3.
