(E)-ethyl 3-(2,4,6-trifluorophenyl)acrylate

反应条件: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Pd/C (0.5 g, 10%, 50% water wet) was added to a solution of ethyl (2E)-3-(2,4,6-trifluorophenyl)-2-propenoate (2.0 g, 8.69 mmol) in ethyl acetate (40 mL) under an argon atmosphere, followed by TEA (2.409 mL, 17.38 mmol) and formic acid (1.666 mL, 43.4 mmol). The reaction mixture was refluxed at 90° C. under argon for 1 h. The reaction mixture was filtered through a celite pad and the filtrate was then washed with water, 5% NaHCO3 solution and brine, before being dried over Na2SO4. Solvent evaporation under reduced pressure yielded the title compound as a pale yellow oil (1.8 g, 89% yield). LCMS: 3.41 min, [M+H+]=232.9 The reaction mixture was filtered through a celite pad the filtrate was then washed with water, 5% NaHCO3 solution and brine before being dried over Na2SO4 Solvent evaporation under reduced pressure

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To the solution of ethyl[bis(methyloxy)phosphoryl]acetate (1.980 mL, 11.99 mmol) in THF-DMF (60 mL, v/v=5:1) at 0° C. was added t-BuOK (1.458 g, 12.99 mmol) portion wise. The resultant mixture was stirred at room temperature for 30 minutes, then mixed with a solution of 2,4,6-trifluorobenzaldehyde (1.6 g, 9.99 mmol) in THF (10 mL) at 0° C. It was allowed to warm to room temperature and the mixture was stirred for 45 min. It was mixed with aqueous ammonium chloride and then extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated. The residue was purified by a flash column chromatography to give the title compound as a pale yellow oil (2.0 g, 87% yield). LCMS: rt=3.52 min, [M+H+]=231.1 extracted with ethyl acetate The organic layer was washed with brine dried over Na2SO4 filtered concentrated The residue was purified by a flash column chromatography
