The palladium-catalyzed borylative cyclization via C—H activation has been developed. By this chemistry, the indole-fused dihydro-pyrrole motif, which is a kind of important unit in natural products and bio-active molecules, could be constructed and installed with a boric ester group. Furthermore, the utilities of products have been illustrated by the study of further transformations. Importantly,
已经开发了通过CH活化的钯催化的硼化环化。通过这种化学方法,可以构建和安装具有硼酸酯基团的吲哚稠合二氢吡咯基序,该基序是天然产物和生物活性分子中的一种重要单元。此外,产品的效用已通过对进一步转化的研究得到说明。重要的是,通过使用手性配体,可以控制这种硼化环化反应的对映选择性。此外,基于 DFT 计算提出了应该通过 Pd(II)/Pd(IV) 催化循环进行的硼化机制。
