By the Reformatsky technique of β-cyclocitral with γ-bromosenecioate, 5-hydroxy-3-methyl-5-(2', 6', 6'-trimethyl-1-1'-cyclohexen-1'-yl)-2-pentenoic acid δ-lactone was obtained. This lactone readily isomerized into cis-β-ionylideneacetic acid, which was led to cis-β-ionylideneethanol by the lithium aluminum hydride reduction. Oxidation of cis-β-ionylideneethanol with manganess dioxide gave trans-β-ionylideneacetaldehyde.
