Two synthetic approaches to the novel C10H16 hydrocarbon tricyclo3,9>decane (1; 2-homotwistbrendane), one of the 19 members of the adamantaneland, and its Lewis-acid-catalyzed rearrangement are described.One route starts from tricyclo3,8>nonan-2-one (2; 2-twistbrendanone).The missing tenth C-atom is introduced by ring enlargement (Tiffeneau-Demjanov method).Starting from methyl 8,9,10-trinorborn-5-ene-2-endo-carboxylate (8), ring enlargement by one C-atom, regio- and stereoselective introduction of a C1 unit to a 2-endo,6-endo-disubstituted bicyclo octane, and ring closure by acyloin condensation are the key steps in the second approach.
