## Abstract The bis[6.3.3]propellane 6 derivative of 2,2′,6,6′‐tetramethylbiphenyl was, in the final stage, synthesized by dehydration, of octaalcohol 5. X‐ray structure analysis revealed the highly symmetric shape of the molecule and disordered oxygen atoms in the tetrahydrofuran rings. The dihedr
## Abstract Formation of (−)‐[4.3.3]propellane 4 from (−)‐14‐hydroxymodhephene (2) proceeds through a Wagner‐Meerwein rearrangement via C3C4 bond‐shift to give a stable intermediate, dimethylcyclohexadienyl cation A, which undergoes deprotonation. Herein, this mechanism was investigated by using a
