We report a stereoselective formal 3 + 2 cycloaddition of cyclopropyl ketones and radical-acceptor alkenes to form polysubstituted cyclopentane derivatives. Catalyzed by a chiral Ti(salen) complex, the cycloaddition occurs via a radical redox-relay mechanism and constructs two C-C bonds and two contiguous stereogenic centers with generally excellent diastereo- and enantioselectivity.
