实验过程
To a sealed tube containing 95.A (0.1059 g, 0.22 mmol), bis(dibenzylideneacetone)palladium (0.0068 g, 0.012 mmol), and CTC-Q-Phos (commercially available from Strem Chemicals) (0.0079 g, 0.011 mmol) was added dry THF (2.1 mL). After 5 minutes, 3-ethoxy-3-oxopropylzinc bromide, 0.5 M solution in THF (0.9 mL, 0.45 mmol) was added dropwise. After 1 hour, the mixture was heated to 80° C. and monitored with TLC and LC-MS. After 16.5 hours, the reaction was cooled to room temperature, and then the organic solvent was removed under reduced pressure. The solid was filtered off, and the solvent was concentrated. The residue was purified by silica gel flash chromatography (0-40% EtOAc/hexane) to afford 95.B (86.2 mg, 78% yield). 1H NMR (500 MHz) (CDCl3) δ ppm 8.10 (1H, d, J=5.4 Hz), 7.41 (1H, dd, J=7.9, 1.8 Hz), 7.33 (2H, dd, J=4.6, 1.5 Hz), 6.98 (1H, m), 6.81 (3H, m), 6.70 (1H, s), 5.52 (1H, t, J=2.0 Hz), 5.42 (2H, s), 4.15 (2H, q, J=7.1 Hz), 3.76 (3H, s), 2.93 (2H, t, J=7.7 Hz), 2.66 (2H, m), 2.25 (2H, td, J=7.0, 2.4 Hz), 1.66 (2H, t, J=7.0 Hz), 1.25 (3H, t, J=7.1 Hz), 0.86 (6H, s).
