Doubling the bet: Two CH bonds become functionalized upon exposure of ω‐aryl propargylic tosylates to Sc(OTf)3 (see scheme). The reaction involves a new domino process that can tolerate both electron‐withdrawing and ‐donating substituents on the arene unit. Different carbo‐ and heterocyclic frameworks can be assembled by using this approach to formally conquer the hydroarylation process.
将赌注加倍:当ω-芳基炔丙基甲苯磺酸酯暴露于Sc(OTf)3时,两个CH键官能化(请参阅方案)。该反应涉及一个新的多米诺骨牌过程,该过程可以耐受芳烃单元上的吸电子和给电子取代基。通过使用这种方法可以正式征服加氢芳构化过程,可以组装不同的碳和杂环骨架。
