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.

A metal‐free CC bond formation method via the oxidative cross‐coupling reaction of isochroman and indolederivatives was established. Various α‐fuctionalized cyclic ethers were achieved in satisfactory yields using di‐tert‐butyl peroxide (DTBP) as the oxidant. This method is also a potentially efficient strategy for the construction of cyclic ether‐containing targets.
