4-Substituted bromobenzoic acids react with 3-thienylacetonitrile under aryne-forming conditions (LDA) to give the corresponding thieno[2,3-f]benzo[cd]indol-4-ones; this constitutes the first reported synthesis of this heretofore unknown tetracyclic heterocycle.
4-取代的溴代苯甲酸在形成芳烃的条件下(LDA)与3-噻吩基乙腈反应,生成相应的噻吩并[2,3- f ]苯并[ cd ]吲哚-4-酮。这构成了迄今为止未知的四环杂环的首次报道的合成。
