実験手順

A mixture of 3-chloro-2-(chloromethyl)prop-1-ene (1.0 g, 8 mmol) and sodium iodide (6.6 g, 44 mmol) in acetone (60 mL) was stirred at room temperature for 20 hours, evaporated under reduced pressure and dissolved in dichloromethane (150 mL) and water (50 mL). The organic layer was dried over sodium sulfate, filtered and evaporated to yield 3-iodo-2-(iodomethyl)prop-1-ene as a reddish oil (2.45 g). To a solution of 2-nitro-1-(2,4,5-trifluorophenyl)ethanone (110 mg, 0.5 mmol) in N,N-dimethylformamide (3 mL), N,N-diisopropylethylamine (0.20 mL) and 3-iodo-2-(iodomethyl)prop-1-ene (170 mg, 0.55 mmol) were added and the mixture was heated at 60° C. for 2.5 hours, evaporated and purified by chromatography on a Biotage Horizon® system (silica, gradient 0-30% dichloromethane in hexane) to yield 3-methylene-5-nitro-6-(2,4,5-trifluorophenyl)-3,4-dihydro-2H-pyran.
