An efficient method for synthesizing thioaurones has been developed using xanthate as an odorless sulfur surrogate. This reaction's key success lies in the use of iodine as a reagent, which promotes the α-iodination followed by cyclization of saturated ketones. This methodology has also been demonstrated with less reactive 2′-bromochalcones in good yield. Synthesis of the red isomer of indigo, i.e
