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
已开发出一种使用黄原酸盐作为无味硫代用品的有效合成硫磺酮的方法。该反应的关键成功在于使用碘作为试剂,它促进了 α-碘化,然后是饱和酮的环化。该方法也已通过反应性较低的 2'-溴查耳酮得到良好的收率。还实现了靛蓝的红色异构体的合成,即靛玉红的硫杂类似物。
