The utility of diazinyl substituted carbodiimides (1a-c) for the synthesis of novel guanidines (2), isothioureas (3), and isoureas (4) is shown. Attempts to determine the stereochemistry of the target compounds using NOE difference spectroscopy or X-ray analysis, respectively, are described.
二嗪基取代的碳二亚胺(的效用1A-1C为新颖胍(合成)2),异硫脲(3),和异脲(4)被示出。描述了尝试分别使用NOE差光谱法或X射线分析法确定目标化合物的立体化学的方法。
