A simple two-step synthesis of triptycene di- and tetracarboxylic acids is reported. Diels-Alder reaction between dimethylanthracenes and appropriate arynes, generated in situ from anthranilic or dimethylanthranilic acid, afforded di- or tetramethyl-triptycenes in 41-69% yields. Subsequent oxidation of the methyl groups with potassium permanganate provided the corresponding triptycene carboxylic acids
报道了三蝶烯二和四羧酸的简单两步合成。二甲基蒽和适当的芳烃之间的狄尔斯-阿尔德反应(由邻氨基苯甲酸或二甲基邻氨基苯甲酸原位产生)以 41-69% 的产率提供二甲基或四甲基三蝶烯。随后用高锰酸钾氧化甲基以86-96%的产率提供相应的三蝶烯羧酸。
