A facile and efficient two-step synthetic route to previously inaccessible 1,3-unsubstituted 2-imino-5-oxooctahydroimidazo[4,5-d]-imidazol-1-ium iodides has been developed using easily accessible thioglycolurils, MeI, and various primary amines, morpholine, or ethylene diamine. The structure of representative products and hydrogen-bonding pattern in their crystals have been investigated by X-ray diffraction
使用容易获得的硫代糖醇,MeI和各种化合物,已经开发了一种简便有效的两步合成路线,以合成先前难以获得的1,3-未取代的2-亚氨基-5-氧代辛基氢咪唑[4,5 - d ]-咪唑-1-碘鎓盐。伯胺,吗啉或乙二胺。通过X射线衍射研究了代表性产物的结构及其晶体中的氢键模式。
