A novel approach for the synthesis of cis/trans-fused perhydroazulenes 13-19 is reported. The stereochemistry of the derivatives of carbene addition products 9a-c/20-22, of the 2,6-disubstituted perhydroazulenes 12a-c/23-25, and that of compounds 26-27 has been studied by single-crystal X-ray crystallography. The hydrogenation of the tropylidene to the perhydroazulene skeleton under various conditions is described. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
