Reaction Steps

5-(3-Benzyloxypropyl)-2-oxo-4-phenyltetrahydro-3-furancarboxylic acid (1 g) was dissolved in a solution (5 ml) prepared from sodium acetate (105 mg), acetic acid (4 ml), formalin (2.92 ml) and diethylamine (1 ml), and the solution was heated on a water bath (100° C.) for 30 minutes. After cooling, the reaction mixture was poured into ice water and extracted with ether. The extract was washed with 5% sodium bicarbonate and water and dried over magnesium sulfate. The solvent was then distilled off to give 5-(3-benzyloxypropyl)-3-methylene-4-phenyltetrahydro-2-furanone (0.7 g) as a colorless oil.
