A general approach for the allylation of oxa- and azabenzonorbornadienes is reported by merging organophotoredox and nickel catalysis. This methodology allowed the diastereoselective allylation of various heterocyclic alkene derivatives with a broader range of allylic acetate compounds compared to previously published procedures. Moreover, no air-sensitive organometallic species and no metal reductants

oxabenzonorbornadienes using dual photoredox/nickelcatalysis has been disclosed. This cascade reaction allowed the preparation of the cis-aminomethyl dihydronaphthalenols without any prefunctionalization or any use of nucleophilic organometallic species. The control of the regio- and stereoselectivity might be explained by a sequence involving insertion of nickel(0) into the C-O bond followed by the formation
