The 7,10-product (βCar-7,10-EPO) results from the attack on C7, during which the hybridization of this carbon atom changes from sp2 to sp3, followed by two 180° rotations around C–C bonds, as indicated, leading to the stabilized allylic-like radicals 2 and 3, respectively; the recombination of 3 via intermediate 4 yields βCar-7,10-EPO.
