The synthesis of the (±)-form of the marine sesquiterpene (–)-Δ9(12)-capnellene (1) by double application of the a-alkynone cyclization is described. Starting with 2, 2, 5-trim ethylcyclopentanone (2), the elaboration of the tricyclo [6.3.0.02,6]undecane C-skeleton of 1 proceeded through the a-alkynone 3, which was cyclized thermally to the bicyclo [3.3.0]octenone 4. For the anellation of the third
