실험 절차
2-Methoxybenzyltriphenylphosphonium bromide was coupled with phthalimide 29 to give (E)-2-(3-(3-(2-methoxystyryl)phenyl)propyl)isoindoline-1,3-dione as a white solid. Yield (0.5590 g, quant.), trans-/cis-isomer ratio 1:1. Trans-isomer: 1H NMR (400 MHz, DMSO-d6) δ 7.81-7.88 (m, 4H), 7.52-7.65 (m, 5H), 6.69-7.41 (m, 4H), 6.57 (d, J=16.8 Hz, 1H), 3.76 (s, 3H), 3.52 (t, J=6.8 Hz, 2H), 2.48 (t, J=8.0 Hz, 2H), 1.91-1.99 (m, 2H).
