草酸双亚胺酰氯的氨解反应。第一部分.与芳香族和脂肪族胺的反应 研究了草酸衍生的双亚胺酰氯2与几种芳香胺和脂肪胺的反应。而芳族伯胺需要通过NH 4热活化,脂肪族伯胺主要在室温下以适度高至良好的产率得到脒3。 从对映体纯胺如(R)-或(S)-1-苯乙胺出发,得到了具有C2对称性的新的纯手性草酸脒3 y和3 z。几种仲胺与双亚胺酰氯2a反应,通过分子内环酰化得到靛红衍生物。新合成的脒3执行系统具有很强的分子动力学,如prototropie和E/Z-相互转换。所有新化合物均经元素分析和光谱方法表征。
On the Aminolysis of Bis-Imidoylchlorides of Oxalic Acid. Part I. Reaction with Aromatic and Aliphatic Amines The reaction between bis-imidoylchlorides 2 derived from oxalic acid and several aromatic and aliphatic amines was investigated. While primary aromatic amines need a thermical activation by refluxing, primary aliphatic amines give mainly at room temperature the amidines 3 in moderatly up to good yields. Proceeding from enantiomeric pure amines e.g. (R)- or (S)-1-phenethylamine the new homochiral oxalic amidines 3y and 3z with C2-symmetry were obtained. Several secondary amines react with the bis-imidoylchloride 2a to give via intramolecular cycloacylation derivatives of isatine. The new synthesized amidines 3 perform systems with a strong molecular dynamic like prototropie and E/Z-interconversion. All new compounds described were characterized by elemental analysis and spectroscopic methods.
