Presumably, the topology of the transition state A is influenced by π-π* interactions of the allylic moieties by precoordination and, therefore, favor the entropic term of the cyclization. In principle a γ,γ′-coupling between C-3 and C-7 is also possible and would lead to the cis configured five-membered ring. However, this would cause an increase of transannular and diaxial interactions of the side chains with the ring system: for this reason, the formation of a nine-membered ring takes place.
