実験手順

To a solution of 1.72 g of (2Z)-4-(acetyloxy)-3-[4-(methylsulfonyl)phenyl]-2-phenylbut-2-enoic acid in 20 mL of CH2Cl2 at 0° C. was added 1.06 g of 4,5-bis(nitrooxy)pentyl alcohol, 225 mg of DMAP and 970 mg of EDCI. The mixture was stirred at RT for 2 h then quenched by addition of NH4Cl sat., extracted with EtOAc, washed with NaHCO3 sat., brine and dried over sodium sulfate. Purification by flash chromatography afforded 1 g of the titled compound as a white solid. 1H NMR (acetone-d6, 500 MHz): δ 7.77 (d, 2H), 7.43 (d, 2H), 7.18-7.16 (m, 3H), 7.08 (dd, 2H), 5.53-5.50 (m, 1H), 5.20 (s, 1H), 4.97 (dd, 1H), 4.69 (dd, 1H), 4.31 (m, 2H), 3.05 (s, 2H), 1.89 (m, 7H).
