YieldReaction ConditionsOperation in experiment
With dmap; trifluoroacetic anhydride;AlCl3; In hexane; dichloromethane; ethyl acetate; 18.1: 2,2,2-Trifluoro-1-(3,4-dimethoxyphenyl)-ethanone 13.8 g (0.10 mol) of 1,2-dimethoxybenzene and 12.2 g (0.10 mol) of 4-dimethylaminopyridine are mixed in 75 ml of CH2Cl2 and cooled in an ice bath. To the solution are added dropwise 21.0 g (0.10 mol) of trifluoroacetic anhydride, followed by 32.0 g (0.24 mol) of AlCl3 by portions. The reaction mixture is stirred at room temperature overnight, poured into ice water, and extracted with CH2Cl2. The organic phase is washed with water, dried over MgSO4, and concentrated. The residue is purified by flash chromatography on silica gel with ethyl acetate and hexane (1:9), yielding 2.9 g of product as white solid.

YieldReaction ConditionsOperation in experiment
With sodium acetate; In ethanol; water; 18.2: 2,2,2-Trifluoro-1-(3,4-dimethoxyphenyl)-ethanone oxime 2.9 g (9.7 mmol) of 2,2,2-trifluoro-1-(3,4-dimethoxyphenyl)-ethanone are dissolved in 12 ml of ethanol at 80 C. To the solution are added dropwise 0.83 g (12.0 mmol) of hydroxylammonium chloride and 1.2 g (15.0 mmol) of sodium acetate dissolved in 6 ml of water. The reaction mixture is refluxed for 7.5 hours, poured into ice water, and extracted with ether. The organic phase is washed with water and brine, dried over MgSO4, and concentrated, yielding 2.3 g of 2,2,2-trifluoro-1-(3,4-dimethoxyphenyl)-ethanone oxime. The crude product is used in the next reaction step without further purification.

YieldReaction ConditionsOperation in experiment
100% A solution of 5 undecan-2-one (306 mg, 1.8 mmol) in 6 THF (8 mL) was cooled to -78 C. , then 7 LDA (2M solution in THF, 1.05 mL, 2.1 mmol) was added slowly. The mixture was stirred at -78 C. for 45 mins. A solution of 8 <strong>[300374-83-8]2,2,2-trifluoro-1-(3,4-dimethoxyphenyl)ethanone</strong> (234 mg, 1.0 mmol) in THF (2 mL) was added slowly. After stirred at -78 C. for 4 hrs, the mixture was warmed to RT for 30 mins. 20 mL of Sat'd aq. NH4Cl was added. This mixture was extracted with diethyl ether (30 ml) twice. The combined ether layer was washed with brine (20 mL), dried over Na2SO4 and concentrated under vacuum. The residue was purified by ISCO flash column (0-10% 9 ethyl acetate/hexanes to afford 10 title compound 404 mg (100%).
