实验步骤: A 15 mL screw top test tube fitted with a PTFE septum cap was purged with argon before addition of CuI (5.0 mg, 0.026 mmol, 2.6 mol %), NaOH (125 mg, 3.12 mmol) and rac-2-amino-1-cyclohexanol HCl (158 mg, 1.04 mmol). 2-Chloro-1-iodobenzene (152 μL, 1.25 mmol) and isopropyl alcohol (1.0 mL) were added, via syringe, under argon. The septum cap was replaced with a solid, Teflon-lined cap and the reaction was stirred magnetically at 90° C. for 48 h. The resulting homogeneous solution was allowed to cool before dilution with 10 mL brine. The reaction mixture was transferred to a separatory funnel and extracted with methylene chloride (3×10 mL). The organics were washed with brine, dried over MgSO4 and concentrated. The crude material was purified by silica gel chromatography using hexanes/ethyl acetate (60:40). The product was obtained as a yellow oil in 91% yield (212.7 mg). cap The septum cap lined cap The reaction mixture was transferred to a separatory funnel extracted with methylene chloride (3×10 mL) The organics were washed with brine dried over MgSO4 concentrated The crude material was purified by silica gel chromatography The product was obtained as a yellow oil in 91% yield (212.7 mg)

实验步骤: Tetrakis(triphenylphosphine)palladium(0) (637 mg, 0.551 mmol), Na2CO3 (5 mL, 1M) and 4-methylbenzene boronic acid (1.5 g, 11.0 mmol) were added to a solution of 2-chloroiodobenzene (1.315 g, 5.514 mmol) in toluene (98 mL) and EtOH (20 mL). The reaction mixture was heated at reflux for 3 h. The cooled solution was diluted with EtOAc, and the organic solution was washed with water (2×) followed by brine (1×). The organic solution was dried over MgSO4, filtered, and concentrated in vacuo. The product was purified by flash chromatography (hexanes to 10% EtOAC/hexanes) to afford 4′-methyl-2-chloro-biphenyl (1.08 g). 1H NMR (CDCl3 400 MHz) δ 7.49–7.21 (m, 8H), 2.39 (s, 3H).

实验步骤: To a stirring solution of 1-chloro-2-iodobenzene (7.05 g, 29.6 mmol) in tetrahydrofuran (Volume: 15 mL) at −15° C. was added isopropylmagnesium chloride (17.24 mL, 34.5 mmol). The mixture was allowed to stir for 30 minutes, at which time 3-bromo-2-fluorobenzaldehyde (5 g, 24.63 mmol) was added. The reaction mixture was stirred overnight. The reaction was quenched with saturated aqueous NH4Cl. The reaction mixture was extracted with EtOAc (3×).
