The conjugated tetraenes 3 and 4 a–c have been prepared and shown to possess an orthogonal structure. This was not only demonstrated by their spectroscopic properties and X‐ray structural analysis of solid representatives (e.g., 4 a–c) but also by the resolution of these chiral compounds by GC and HPLC chromatography using various chiral selector systems. The chemical behavior of the typical tetraene
共轭四烯3和4 - ç已经制备并显示出具有正交结构。(例如,这不仅可以通过光谱性质和固体的代表X射线结构分析表明4 - C ^),而且还由通过GC和HPLC色谱法,使用各种手性选择系统中,这些手性化合物的分辨率。典型的四烯的化学行为4已经使用溴化,氢化,环氧化,和相片平衡反应的研究。
