反应详情

The phenol from Example 6B (68 mg, 0.2 mmol) was dissolved in DMF (0.4 mL) and K2CO3 (41 mg, 0.2 mmol) and allyl bromide (36 mg, 0.3 mmol) were added at ambient temperature. The reaction mixture was worked up and purified by column chromatography to provide the titled compound (15 mg, 20%). 1H NMR (400 MHz, DMSO-D6) δ 9.59 (s, 1H), 7.39 (d, J=9.2 Hz, 2H), 7.05 (t, J=8.0 Hz, 1H), 6.75 (d, J=8.0 Hz, 1H), 6.70 (d, J=8.0 Hz, 1H), 6.61 (d, J=9.2 Hz, 2H), 6.05 (ddddd, 5.2, 5.2, 10.8, 16.0 Hz, 1H), 5.39 (dddd, J=1.2, 1.2, 1.2, 15.2 Hz, 1H), 5.24 (dddd, J=1.2, 1.2, 1.2, 10.4 Hz, 1H), 4.55 (m, 2H), 3.28 (q, J=6.8 Hz, 4H), 2.3 (m, 1H), 2.79 (m, 2H), 2.61 (m, 2H), 1.99 (m, 1H), 1.69 (m, 1H), and 1.06 (t, J=6.8 Hz, 6H). MS (ESI) positive ion 379 (M+H)+; negative ion 377 (M−H)−.
