Reaction Conditions

Reaction Steps

To a 0° C. mixture of methyl triphenylphosphonium bromide (236 mg, 0.66 mmol) in THF (8 mL) was added dropwise n-BuLi (0.27 mL of a 2.5 M solution in hexane, 0.66 mmol). The reaction mixture was stirred at 0° C. for 30 min, and a solution of 4-(1-(3-phenoxyphenyl)-2-oxabicyclo[2.2.2]octan-4-yl)butanal (116 mg, 0.33 mmol) in THF (2 mL) was added at 0° C. The reaction mixture was warmed to rt and stirred for 2 h, then was quenched with sat′d aq. NH4Cl, and extracted with EtOAc. The organic layer was washed with brine, dried (MgSO4), and concentrated in vacuo. The crude material was purified by flash chromatography (SiO2; gradient from 0 to 30% EtOAc:hexanes) to afford the title compound as a colorless oil (94 mg; 81% yield). 1H NMR (400 MHz, CDCl3) δ 7.34-7.23 (m, 4H), 7.16-7.05 (m, 2H), 6.98 (dd, J=8.7, 1.0 Hz, 2H), 6.83 (ddd, J=8.0, 2.4, 1.0 Hz, 1H), 5.79 (ddt, J=17.0, 10.3, 6.6 Hz, 1H), 5.03-4.93 (m, 1H), 3.79 (s, 2H), 2.06-1.93 (m, 5H), 1.70-1.52 (m, 6H), 1.48-1.22 (m, 3H), 1.21-1.03 (m, 2H).
