1-(2-iodophenyl)ethanone

反応条件: temp:-30.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of diisopropylamine (1.6 mL, 11.1 mmol) in THF (38 mL) at 0° C. was added n-BuLi (4.1 mL, 10.2 mmol) under an atmosphere of N2. After 30 min the solution was cooled to −30° C. and a solution of 1-(2-iodophenyl)ethanone (2.27 g, 9.23 mmol) in THF (6 mL) was added dropwise to the mixture and was stirred for 45 min at −30° C. The mixture was cooled to −78° C. and cyclohexylcarboxaldehyde (1.2 mL, 9.69 mmol) was added dropwise and the mixture was allowed to warm to −40° C. over 2 h. The reaction was quenched by the addition of saturated aqueous NH4Cl. The aqueous layer was extracted with EtOAc (2×50 mL). The combined organic layers were washed with brine, dried (Na2SO4), filtered and concentrated. The residue was purified by flash column chromatography to afford the title compound as yellow oil (2.56 g, 78%). 1H NMR: 1.02-1.27 (m, 4H), 1.41-1.49 (m, 1H), 1.66-1.76 (m, 4H), 1.89 (d, 1H, J=12.4 Hz), 2.88 (d, 1H, J=3.2 Hz), 2.98 (dd, 1H, J=9.2 Hz, 17.2 Hz), 3.13 (dd, 1H, J=2.0 Hz, 17.2 Hz), 3.99-4.01 (m, 1H), 7.11-7.15 (m, 1H), 7.42 (d, 2H, J=4.4 Hz), 7.93 (d, 1H, J=8.0 Hz). The mixture was cooled to −78° C. to warm to −40° C. over 2 h The reaction was quenched by the addition of saturated aqueous NH4Cl The aqueous layer was extracted with EtOAc (2×50 mL) The combined organic layers were washed with brine dried (Na2SO4) filtered concentrated The residue was purified by flash column chromatography

実験手順: To Resin A (30 mg) was added THF (0.4 ml). To the mixture was added 9-BBN (0.5M in THF, 0.4 ml). The mixture was stirred at room temperature for 4 hours. To the mixture was added an aqueous solution of potassium carbonate (2M, 0.1 ml), 2-acetyliodobenzene (41 mg, 0.2 mmol) and PdCl2(dppf) (3 mg). The mixture was stirred at 50° C. for 20 hours. The obtained resin was washed with DMF, water, methanol and methylene chloride to give Resin B. The mixture was stirred at 50° C. for 20 hours The obtained resin was washed with DMF, water, methanol and methylene chloride
