  Direct coupling of arenes and iodoarenes catalyzed by a rhodium complex with a strongly π-accepting phosphite ligand

  摘要：

  A new rhodium-based catalytic system for the direct C-H coupling of arenes and iodoarenes that shows high activity with reasonably broad scope was developed. Under the catalytic influence of RhCl(CO){P[OCH(CF3)(2)](3)}(2) and Ag2CO3, the direct C-H arylation of heteroarenes and arenes took place with iodoarenes to afford a range of biaryls in good to excellent yields with high regioselectivity. Thiophenes, furans, pyrroles, indoles, and alkoxybenzenes are applicable to this arylation protocol. (C) 2008 Elsevier Ltd. All rights reserved.

• β-Selective C–H Arylation of Pyrroles Leading to Concise Syntheses of Lamellarins C and I

  The first general β-selective C-H arylation of pyrroles has been developed by using a rhodium catalyst. This C-H arylation reaction, which is retrosynthetically straightforward but results in unusual regioselectivity, could result in de novo syntheses of pyrrole-derived natural products and pharmaceuticals. As such, we have successfully synthesized polycyclic marine pyrrole alkaloids, lamellarins C

  吡咯的第一个通用 β 选择性 CH 芳基化已通过使用铑催化剂开发。这种 CH 芳基化反应在逆向合成上很简单，但会产生不寻常的区域选择性，可以从头合成吡咯衍生的天然产物和药物。因此，我们通过使用吡咯与芳基碘化物的这种β-选择性芳基化（CH / Cl 偶联）和新的双 CH / CH 偶联作为关键步骤，成功合成了多环海洋吡咯生物碱、层状菌素 C 和 I。

  A new method for the catalytic C-H arylation of heteroarenes and arenes that manifests high activity paired with reasonably broad scope was developed. Under the catalytic influence of RhCl(CO)P[OCH(CF3)2]3}2 and Ag2CO3, the direct C-H arylation of heteroarenes/arenes with aryl/heteroaryl iodides took place to afford a range of biaryls in good to excellent yields with high regioselectivity. Thiophenes, furans, pyrroles, indoles, and alkoxybenzenes are applicable in this arylation protocol.
