説明
<jats:p><jats:bold>On the Way to Macrocyclic <jats:italic>para‐</jats:italic>Phenylenes</jats:bold></jats:p><jats:p>Strategies are presented to synthesize the hitherto unknown [O<jats:sub>n</jats:sub>]Paracyclophanes <jats:bold>1</jats:bold>. Open chain belt‐type molecules based on 1,4‐connected carbocyclic six‐membered rings were prepared. Functionalization of the outer rings in 4‐position is the prerequisite for cyclization or lengthening of the molecular belts. In order to obtain the macrocyclic target molecules <jats:bold>1</jats:bold>, well preorganized <jats:italic>cis</jats:italic>‐isomers of 1,4‐disubstituted cyclohexanes were prepared. X‐ray structural analyses reveal the static stereochemistry of the intermediates <jats:bold>8, 9, 17, 18</jats:bold>, and <jats:bold>24</jats:bold>. The macrocyclic hydrocarbon <jats:bold>29</jats:bold> containing five cyclohexylidene units was detected.</jats:p>
