We present a strategy that difunctionalizes unactivated olefins in 1,2-positions with two carbon-based entities. This method utilizes alkyl/arylzinc reagents derived from olefin-tethered alkyl/aryl halides that undergo radical cyclization to generate C(sp3)-Cu complexes in situ, which are intercepted with aryl and heteroaryl iodides. A variety of (arylmethyl)carbo- and heterocycles (N, O) can be synthesized
我们提出了一种策略,用两个碳基实体对 1,2 位的未活化烯烃进行双官能化。该方法利用衍生自烯烃系烷基/芳基卤化物的烷基/芳基锌试剂,这些烷基/芳基卤化物经过自由基环化以原位生成 C(sp3)-Cu 配合物,其被芳基和杂芳基碘化物拦截。使用这种新方法可以合成各种(芳甲基)碳环和杂环(N,O)。
