A Lewis-acid-mediated intramolecular trifluoromethylthiolation of alkenes with phenols that can offer direct access to SCF3-containing chromane and dihydrobenzofuran compounds was disclosed for the first time. Numerous SCF3-containing chromanes were obtained in moderate to good yields using γ-substituted 2-allyphenols as substrates. Meanwhile, various SCF3-containing dihydrobenzofurans with oxa-quaternary
首次公开了路易斯酸介导的烯烃与酚的分子内三氟甲基硫醇化,该酚可以直接进入含SCF 3的苯并二氢呋喃和二氢苯并呋喃化合物。使用γ-取代的2-烯丙基苯酚作为底物,以中等至良好的产率获得了许多含SCF 3的苯并二氢吡喃。同时,还使用β-取代的2-烯丙基酚作为底物以中等至良好的产率递送了具有氧杂-季中心的各种含SCF 3的二氢苯并呋喃。
