Abstrakt: |
The title compound was synthesized by a two-fold BOP-Cl mediated esterification of o-phenylenediacetic acid with catechol. The presence of the bridging esters results in a considerable change in the conformational landscape of the cyclophane system in comparison to the parent [3.3]orthocyclophane and related systems. A conformer search at the AM1 level identified six low energy conformers. The one observed in the solid state was calculated to be the second lowest in energy, 0.32 kcal/mol above the calculated global minimum. |
