Biscyclopropanation : Dienynes containing a cyclohexadienyl unit can be converted into tetracyclo[3.3.0.0 2,8 .0 4,6 ]octanes by treatment with an (N‐heterocyclic carbene)gold catalyst. When the dienynes bear an open‐chain diene instead of cyclohexadiene, open‐cage compounds, with two sides missing from the cage, are obtained.
