An iron-catalyzed perezone-type [5 + 2] cycloaddition toward tricyclo[6.3.1.01,6]dodecane scaffolds is presented, furnishing cycloadducts with two new C–C bonds and three to four stereogenic centers generated with typically good yields and excellent diastereoselectivities. Two independent conditions, catalytic FeCl3/PhCO3tBu (0.5 equiv/1 equiv) and stoichiometric FeCl3(2 equiv), have been respectively
