The efficient synthesis of all-cis-[5.5.5.5]fenestrane (2) from the readily available intermediate 3 allowed the electron-diffraction analysis of 2. This structure analysis revealed long C-C bonds in the central C(C), fragment and a twist-envelope conformation for the four cyclopentane substructures

## Abstract The synthesis of (all‐__cis__)‐[5.5.5.5]fenestrane (**3**) from dicyclopentadiene is reported. Key step is the Pd‐catalyzed reductive deoxygenation of an appropriately substituted cyclooctanone, which leads to transannular C,C‐bond formation.
