A superacid (triflic acid) promoted dual C–C bond formation via intermolecular Friedel–Crafts alkylation (Michael addition type) and intramolecular acylation for the efficient synthesis of 3-substituted indan-1-ones is presented. This method was successful in activating ethyl cinnamates towards dual aromatic electrophilic substitution. Moreover, it enabled us to synthesize novel spirotetracyclic systems
超强酸(三氟甲磺酸)通过分子间 Friedel-Crafts 烷基化(迈克尔加成型)和分子内酰化促进双 C-C 键形成,用于有效合成 3-取代的茚满-1-酮。该方法成功地将肉桂酸乙酯活化为双芳香族亲电取代。此外,它使我们能够合成新的螺四环系统。
