Abstract A ring-opening process of 4-imino-1,3-thiazetidin-2-ones with NH2OH·HCl was described for the first time. Two different scaffolds of imidodicarbonic diamide were obtained selectively in good yields in the presence of organic base. The obtained imidodicarbonic diamides were demonstrated by X-ray diffraction analysis.
摘要首次描述了4-亚氨基-1,3-噻嗪丁-2-酮与NH2OH·HCl的开环过程。在有机碱存在下,以高收率选择性地获得了两个不同的亚氨基二碳二酰胺支架。通过X射线衍射分析证明所获得的亚氨基二碳二酰胺。
