実験手順
To a mixture of copper (I) iodide (960 mg, 5.0 mmol) and THF (20 mL) was added N,N,N′,N′-tetramethylethylenediamine (0.83 mL, 5.5 mmol) and the resulting mixture was stirred at room temperature for 10 min. then cooled to −78° C. Phenylmagnesium bromide (5.0 mL, 1M in THF, 5.0 mmol) was added and the resulting mixture stirred at −78° C. for 15 min. A solution of di-n-butylboron triflate (3.0 mL, 1M in diethyl ether, 3.0 mmol) and (E)-(4S,5R)-1-(3-[4-methanesulfonylphenyl]acryloyl)-3,4-dimethyl-5-phenyl-imidazolidin-2-one (Method D, 1.0 g, 2.51 mmol) in THF (15 mL) was added and the resulting mixture was stirred whilst allowing to warm to room temperature for 18 h. The reaction mixture was washed with saturated aqueous ammonium chloride, water and brine, dried (MgSO4) and evaporated. The residue was purified by eluting through a 20 g Bond Elut with gradient of isohexane to ethyl acetate giving the sub-titled compound (1.49 g, 100%); NMR (CDCl3): 0.78 (d, 3H), 2.82 (s, 3H), 3.00 (s, 3H), 3.78 (dd, 1H), 3.80 (m, 1H), 3.98 (dd, 1H), 4.72 (m, 1H), 5.19 (d, 1H), 6.99 (m, 2H), 7.22 (m, 8H), 7.48 (d, 2H), 7.79 (d, 2H); MS: 477 (MH+).
