An efficient method for an iron catalyzed oxidative indolation and methoxyphenylation of N-protected tetrahydroisoquinolines and isochroman is described including subsequent facile deprotection.

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 coppercatalysis.
