A highly efficient, transition-metal- and light-free approach to polyheterocycles via regioselective cascade radical cyclization is developed. The redox-neutral protocol has a broad substrate scope with good functional group tolerance probably undergoes SET process, which initiated by catalytic amounts of quinone in combination 2.0 equiv.
