protocol for the formation of substituted aminothiatriazoles from thiocarbamoylimidazolium salts is outlined. Thiocarbamoylimidazolium salts are synthesized from the corresponding amines by treatment with thiocarbonyldiimidazole (TCDI) followed by methylation with iodomethane. Thiocarbamoylimidazolium salts are shown to act as thiocarbamoyl cation equivalents. Substitution of the salts by azide anion
概述了从硫代氨基甲酰咪唑盐形成取代的氨基噻唑的新方案。硫代氨基甲酰咪唑鎓盐是通过用硫代羰基二咪唑(TCDI)处理,然后用碘甲烷甲基化,由相应的胺合成的。硫代氨基甲酰咪唑鎓盐显示为硫代氨基甲酰基阳离子等效物。用叠氮化物阴离子取代盐,然后进行电环化,以良好或极好的收率得到取代的氨基噻三唑。
