Cyclooctene 2.2.2 cyclophane

Fig. 1. Plane of Chirality Enantio-morphous figures and corresponding torsional angles A—X—Y—Z 7). Molecular examples ([n]paracyclophane, [2.2]meta-cyclophane, bridged[10]anulene and ( )-cyclooctene) with descriptors (/ , S)...

On the basis of this definition (Fig. 1) the following classes of chiral compounds will be treated in this article cyclophanes, bridged anulenes and [8]anulenes, and ( )-cyclooctene and related structures. As mentioned above, metallocenes will be excluded. 

Planar chirality may originate if an appropriately substituted planar group of atoms or ring system is bridged by a linker-chain extending into the space above or below this plane (Figure 1.30). Typical examples of the planar chirality are substituted ferrocenes, cyclophanes, or alkenes (e.g., (E)-cyclooctene Figure 1.28).
