Various 2,3-disubstituted 6,7-thienobenzynes have been efficiently generated from the corresponding -silylaryl triflate-type precursors by activation with fluoride ions. The method has expanded the scope of synthesizable multisubstituted benzothiophenes, including those with various heteroatom substituents, and can be applied to the synthesis of EP4 antagonist analogs.
通过氟离子活化,已从相应的硅烷基芳基三氟甲磺酸酯型前体高效生成了各种2,3-二取代的6,7-噻吩并苯炔。该方法扩大了可合成的多取代苯并噻吩的范围,包括那些带有各种杂原子取代基的苯并噻吩,并且可应用于EP4拮抗剂类似物的合成。
