実験手順: Boron tribromide (1.2 mL, 12.69 mol) was slowly added to a dichloromethane solution (40 mL) of 1-phenylpentane-1,5-diol (1.89 g, 10.52 mmol) at 0° C. The reaction mixture was stirred for one hour and quenched with water. The aqueous layer was extracted with dichloromethane (3×10 mL), and the combined organics were dried (magnesium sulfate). The residue was purified by column chromatography on silica gel, eluting with 0-100% ethyl acetate/hexanes to give the title compound as a yellow oil. 1H NMR (500 MHz, CDCl3) δ 1.33-1.44 (m, 1H), 1.52-1.70 (m, 2H), 1.90-2.00 (m, 1H), 2.13-2.22 (m, 1H), 2.27-2.36 (m, 1H), 3.65 (t, J=6.3 Hz, 2H), 4.96 (dd, J=6.9, 8.0 Hz, 1H), 7.24-7.30 (m, 1H), 7.33 (t, J=7.8 Hz, 2H), 7.39 (d, J=7.1 Hz, 2H). quenched with water The aqueous layer was extracted with dichloromethane (3×10 mL) the combined organics were dried (magnesium sulfate) The residue was purified by column chromatography on silica gel eluting with 0-100% ethyl acetate/hexanes
