    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
