摘要：

The structures of 10,10-(ethylenedioxy)hexacyclo-[10.2.1.0(2,11).0(4,9).0(4,14).0(9,13)]pentadeca-5,7-dien-3-one and 10,10-diisopropoxyhexacyclo[10.2.1.0(2,11).04,9.-0(4,14).0(9,13)]pentadeca-5,7-dien-3-one are reported. In each structure the cyclohexadiene ring is planar. Bonding geometries are similar to those found in other cage structures, except for elongations of the C4-C9 propellane-type bonds due to the fusion of the diene rings. A slight flattening of the boat conformations of the unbridged six-membered rings is observed in the acetals relative to the parent dione.
