An unexpected cyclization of thioamides with p-quinone methides promoted by acridinium salt under the irradiation of visible light furnished 1,2,4-dithiazoles in moderate to good yields. In addition, the reaction of the obtained 1,2,4-dithiazoles with isocyanides offered a new entry for the synthesis of thiazol-5(4H)-imines in moderate yields.
在可见光的照射下,a啶盐促进的对苯二甲酰甲基对硫酰胺的意外环化作用,以中等至良好的产率提供了1,2,4-二噻唑。此外,所得的1,2,4-二噻唑与异氰酸酯的反应为以中等收率合成噻唑-5(4 H)-亚胺提供了新的条件。
