摘要：

The direct synthesis of the fused ring systems II (R = Me, H) and the decalin 14 are described. The use of a planar. tether control group (either aromatic ring or double bond) greatly facilitates the key Diels-Alder cycloadditions. A second intermolecular cycloaddition of 14 with cyclopentadiene afforded the tetracyclic adduct 17. The interaction between the allylic ethers and diene substituents influences the facial selectivity observed in these examples. (C) 1997, Elsevier Science Ltd.
