实验步骤: In a 350 mL pressure vessel equipped with a stir bar was placed 3-hydroxy-4-methoxy-benzaldehyde (15) (1.5 g, 9.86 mmol), 3-iodo-benzonitrile (3.39 g, 14.8 mmol), cesium carbonate (3.21 g, 9.86 mmol), N,N-dimethylglycine (275 mg, 1.97 mmol), copper(I) iodide (188 mg, 0.986 mmol) and 1,4-dioxane (55 mL). The mixture was heated to 100° C. for 46 hours. The reaction was cooled to room temperature, quenched with water (300 mL) and then extracted with ethyl acetate (3×200 mL). The organic portions were combined, washed with brine (300 mL), dried (MgSO4) and concentrated. The crude material was purified by silica gel column chromatography utilizing 35%, 50%, 75% ethyl acetate/hexanes to produce 1.09 g (42% yield) of (16) as a white solid.

实验步骤: 3-Iodobenzonitrile (3.76 g, 16.41 mmol) dissolved in tetrahydrofuran (1.5 ml) was cooled to −30° C. A solution of isopropylmagnesium chloride in tetrahydrofuran (2 M, 8.84 ml, 17.67 mmol) was added dropwise at −30° C. over 25 min. The reaction mixture was cooled to −78° C. A solution of (E)-1-chloro-4(1-(2-nitrovinyl)cyclobutyl)benzene (3.0 g, 12.62 mmol) in tetrahydrofuran (0.5 ml) was added dropwise. Aqueous work-up yielded the desired product which was used without further purification for the next step. Yield: 3.3 g (8.71 mmol, 69%, purity: 90% by HPLC) The reaction mixture was cooled to −78° C

实验步骤: A mixture of 3-iodobenzonitrile (10.0 g), copper(I) iodide (166 mg), triphenylphosphine (572 mg), tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (904 mg), propargyl alcohol (2.83 ml), diisopropylethylamine (30.5 ml) and tetrahydrofuran (170 ml) was stirred at room temperature for 23 hr. The reaction mixture was added to brine, and the mixture was extracted with ethyl acetate, washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=95:5-67:33) to give the object product (5.59 g) as a brown solid. the mixture was extracted with ethyl acetate washed with saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (hexane:ethyl acetate=95:5-67:33)

实验步骤: A test tube was charged with CuI (20 mg, 0.10 mmol, 10 mol %), 1,10-phenanthroline (36 mg, 0.20 mmol, 20 mol %), Cs2CO3 (652 mg, 2.0 mmol), 3-iodobenzonitrile (229 mg, 1.0 5 mmol), methanol (162 μL, 4.0 mmol) and toluene (1 mL). The test tube was sealed and the reaction mixture was stirred at 110° C. for 23 h. The resulting suspension was cooled to room temperature and filtered through a 0.5×1 cm pad of silica gel eluting with diethyl ether. The filtrate was concentrated. Purification of the residue by flash chromatography on silica gel (2×20 cm; pentane/diethyl ether 5:1) provided 111 mg (84% yield) of the title compound as a colorless oil.
