either simple copper or iron catalysts. N-protected and unprotected tetrahydroisoquinolines (THIQ) could be used as starting materials. Extension of the substrate scope of the pronucleophile from indoles to pyrroles and electron-rich arenes was realized. Additionally, methoxyphenylation is not limited to THIQ but can be carried out on isochroman as well, again employing iron and copper catalysis.
使用简单的铜或铁催化剂开发了一种高度简便、直接的 1-(3-吲哚基)-四氢异喹啉合成方法。N-保护和未保护的四氢异喹啉(THIQ)可用作起始材料。实现了亲核试剂的底物范围从吲哚扩展到吡咯和富电子芳烃。此外,甲氧基苯基化不限于 THIQ,也可以在异色满上进行,同样采用铁和铜催化。
