Abstract

Here, we report a practical method to selectively access silylated pyrrolo[1,2-a]indoles using alkenyl indoles and readily available silanes through a radical cascade cyclization. The reaction proceeds through an unusual intermolecular polarity-mismatched addition of a nucleophilic silyl radical to e-rich alkene SOMOphiles via a coordination-assisted interaction. The scope and functional group compatibility of the protocol as well as a detailed mechanistic investigation are presented.

未活化烯烃的化学选择性自由基级联极性错配硅烷芳香化反应

在此，我们报告了一种实用的方法，利用烯基吲哚和容易获得的硅烷，通过自由基级联环化，选择性地获得硅烷化的吡咯并[1,2-a]吲哚。该反应是通过亲核硅烷自由基与富含 e 的烯 SOMOphiles 在配位辅助作用下发生不寻常的分子间极性错配加成反应而进行的。本文介绍了该方案的范围、官能团兼容性以及详细的机理研究。
