Isomeric 3- or 4-chlorotriptycene-7-carboxylic acid was synthesized from sodium anthraquinone-β-sulfonate and resolved with quinidine methohydroxide. The absolute configurations of (−)-3-chloro- and (−)-4-chlorotriptycene-7-carboxylic acids could be determined to be 1<I>S</I>,6<I>S</I> and 1<I>S</I>,6<I>R</I>, respectively, by the chemical correlation with (+)-2,5-dimethoxy-8-chlorotriptycene whose absolute configuration was proved to be 1<I>R</I>,6<I>S</I> by X-ray and chemical means.
