An intra-molecular Claisen-like cyclization of ethyl 2-acet-oxy-4,4-dimethyl-1-(3-methyl-but-2-en-yl)cyclo-hex-2-enecarboxylate followed by dialkyl-ation yielded the bicyclic title compound, C(23)H(26)O(4). In both of the fused six-membered rings exist fragments of four atoms which are planar, whereas the remaining two atoms deviate by up to 0.682 (3) Å on one side of the plane of the ring cont...
