Reaction Conditions

Reaction Steps

A tetrahydrofuran (25 mL) solution of trimethyl phosphonoacetate (4.67 g, 25.1 mmol) was added dropwise at 0° C. over 1 hour to a tetrahydrofuran (25 mL) suspension of sodium hydride (1.04 g, 63%, 27.4 mmol). To the mixture, tetrahydrofuran (25 mL) was further added, and the mixture was then stirred at 0° C. for 1 hour. To this solution, a tetrahydrofuran (25 mL) solution of 6-hepten-3-one (2.56 g, 22.8 mmol) was added dropwise at 0° C. over 20 minutes, and the mixture was stirred at room temperature for 2.5 hours and subsequently stirred at 65° C. for 3 hours. The mixture was treated with water, and volatile portions were then distilled off under reduced pressure, followed by extraction with hexane. The organic layer was dried over anhydrous magnesium sulfate. Then, the solvent was distilled off under reduced pressure to obtain the compound of interest as a pale yellow oil substance (3.04 g, 79%).
