Mander reductive alkylation of methyl 2-methoxybenzoate with prenyl bromide and hydrolysis of the enolether afforded methyl 6-oxo-1-prenyl-2-cyclohexenecarboxylate. This was converted in five steps (reduction of the ketone, saponification, iodolactonization, ozonolysis, and intramolecular aldol reaction) to a spiro lactone cyclopentenal. An efficient first synthesis of (+/-)-vibralactone was completed
