indoles and elemental sulfur has been reported. The present approach produces a range of structurally valuable fused thienoindoles in 51–78% yield under transition-metal-free conditions, which may have potential applications in pharmaceutical industry and organic functional materials. In this work, the double C−S bonds formation is achieved via base promoted direct sulfuration of C−H bonds with elemental
