Flavin-dependent 'ene'-reductases (ERED) can generate stabilized alkyl radicals when irradiated with visible light, however, they are not known to form unstabilized radicals. Here, we report an enantioselective radical cyclization using alkyl iodides as precursors to unstabilized nucleophilic radicals. Evidence suggests this species is accessed by photoexcitation of a charge-transfer complex that forms between flavin
