The syntheses of prenylated arenes and 2,2‐dimethylchromans using a Friedel–Crafts‐type coupling between activated arenes and isoprene is reported. A combination of catalytic amounts of FeCl 3 and AgBF 4 promotes a regioselective prenylation event followed by a cyclization to form a 2,2‐dimethylchroman structure. The method avoids isoprene polymerization and allows the facile late‐stage derivatization of biologically active motifs.
