dihydronaphthopyran derivatives were obtained in good yield by the regio‐ and stereoselective annulation of ortho‐naphthoquinone methides with allylsilanes. The ortho‐naphthoquinone methides were generated in situ from 1‐siloxymethyl‐1,4‐epoxy‐1,4‐dihydronaphthalenes under FeCl3 catalysis (see scheme; allyl‐TMS=allyltrimethylsilane, TBS=tert‐butyldimethylsilyl, TMS=trimethylsilyl).
