Reaction Steps

To a solution of methyl 2-acetyl-5,9-dimethyl-10-(methoxymethyl)oxy-4,8-decadienate (420 mg, 1.37 mmol) in methylsulfoxide (4 ml) were added sodium chloride (160 mg, 2.74 mmol) and water (0.1 ml), and the mixture was stirred at 150° C. After five hours, the reaction mixture was allowed to cool to room temperature, and water (10 ml) was added thereto. The product was extracted with ether (20 ml×2). The extract was dried over Na2SO4, and concentrated to give a residue, which was then purified with silica gel column chromatography to obtain 6,10-dimethyl-11-(methoxymethyl)oxy- 5,9-undecadien-2-one (358 mg, 67%),
