実験手順
To a stirred solution of 3-phenoxybenzaldehyde (2 g, 10.09 mmol) in THF (15 mL) at −78° C. was added phenyllithium (6.73 mL, 1.8M solution in cyclohexane-ether) dropwise. After stirring under argon at −78° C. for 4 hrs, the reaction was quenched with water and extracted with diethyl ether. The organic layer was washed with brine, dried with magnesium sulfate, filtered, and concentrated under reduced pressure to give the crude product. The crude mixture was purified via flash SiO2 chromatography (ethyl acetate/hexanes (10%/90%) to (20%/80%)) to give 128 (2.79 g, 86% yield): 1H-NMR (400 MHz, chloroform-d) δ 6.87-7.38 (m, 10 H), 7.09 (m, 1 H), 6.99 (app d, J=7.3 Hz, 1 H), 6.88 (m, J=8.6, 2.2 Hz, 1 H), 5.81 (s, 4 H).
