Abstractmagnified imageThe silver‐catalyzed direct activation of allylic alcohols as electrophilic partners for intramolecular Friedel–Crafts alkylation of arenes is described. Use of silver triflate (AgOTf; 10 mol%) enabled functionalized 1‐vinyl‐1,2,3,4‐tetrahydronaphthalenes and a 4‐vinyl‐1,2,3,4‐tetrahydroisoquinoline to be isolated in good yields with high levels of regiochemistry, under a ligand‐free regime.
