A single and simple ortho‐sulfonyl benzonitrile template was developed to achieve remote C−H olefination of six different classes of N‐heterocycles. We demonstrate that, by varying precatalysts and conditions, the same template can be applied to the remote C−H activation of six structurally distinct heterocyclic scaffolds, and the site‐selectivity can be predicted based on distance and geometry. Furthermore
开发了一个简单的邻磺酰基苯甲腈模板,以实现六种不同类别的N-杂环的远程CH H烯化反应。我们证明,通过改变预催化剂和条件,相同的模板可以应用于六个结构上不同的杂环支架的远程CH活化,并且可以根据距离和几何形状预测位点选择性。此外,这项新进展表明,通过具有较小环尺寸的大环palpalpalation过程,可以进行模板定向的远程CH活化。
