Bicarbocyclic fused system

A computationally designed Rh(I)-catalyzed two component [5+2+1] cycloaddition of allyl cyclopropylallyl ether and CO was shown to give cyclooctenones fused with a tetrahydrofuran ring <07JA10060>. On the other hand, palladium-catalyzed intramolecular [4+3] cycloaddition of 1,6-diene systems as shown below gave rise to mixtures of 5,7- and 5,5-bicarbocycles <07JA11026>.
