In the presence of a protonated cinchonine derivative, radicaladdition reactions proceeded efficiently, affording addition adducts in high yields with an extremely high enantioselectivity. The chiralammonium salt was recyclable after a simple aqueous workup. The reaction provides environmentally benign reaction conditions.
