To a stirred solution of 2-allyl-6-nitrophenol (100 mg, 0.0006 mol) in acetone (4 mL, 0.06 mol) at 0° C. in an ice bath was added potassium carbonate (0.092 g, 0.00067 mol) followed by 3-iodo-1-propene (0.11 g, 0.00067 mol) under an atmosphere of nitrogen. The reaction mixture was stirred for 1 h at 0° C. then warmed to room temperature overnight. The reaction mixture was diluted with ethyl acetate and washed with 10% HCl, water, dried over magnesium sulfate and concentrated in vacuo. The reaction mixture was purified by ISCO chromatography on silica gel (12 g) using ethyl acetate-hexane (10%-50%) to give 1-allyl-2-allyloxy-3-nitrobenzene as a yellow oil (93 mg, 80%). 1H NMR (400 MHz, CDCl3) δ 7.69 (d, 1H, J=8.0 Hz), 7.44 (d, 1H, J=7.8 Hz), 7.16 (t, 1H, J=8.08, 7.8 Hz), 5.90-6.13 (m, 2H), 5.40 (d, 1H, J=17 Hz), 5.29 (d, 1H, J=10 Hz), 5.15 (d, 1H, J=10 Hz), 5.09 (d, 1H, J=17 Hz), 4.50 (d, 2H, J=5.8 Hz), 3.49 (d, 2H, J=6.3 Hz).
