A synthesis of the natural terpenoid spirolactone (±)-andirolactone (1) is described. Condensation of dimethyl malonate (9) with 1-acetyl-4-methyl-3-cyclohexen-1-ol (3), prepared by Diels-Alder reaction of olefin 5 and isoprene (4), and thermal decarboxylation of the resulting spirolactone 10, afforded 1 in 46 % overall yield.
