実験手順

A solution mixture of 6 (0.20 g, 0.8 mmol), 3a (0.33 g, 1.1 mmol) and piperidine (0.1 mL) in ethanol (40 mL) was heated to reflux overnight. After cooling down to room temperature, the organic solvent was removed. The residue was purified by precipitation from methanol and ethyl acetate to afford SLE (0.22 g) in 53% yield.1H NMR (400 MHz, DMSO-d6) δ 9.34 (d, J=8.4 Hz, 1H), 9.15 (d, J=8.4 Hz, 1H), 8.86 (s, 1H), 8.54-8.51 (m, 2H), 8.44 (d, J=16 Hz, 1H), 8.36 (d, J=16 Hz, 1H), 8.28-8.23 (m, 2H), 8.12 (d, J=8.0 Hz, 1H), 8.05 (t, J=7.6 Hz, 1H), 7.77 (d, J=8.4 Hz, 1H), 7.70 (d, J=8.4 Hz, 1H), 7.52 (t, J=7.6 Hz, 1H), 7.31 (t, J=7.6 Hz, 1H), 4.99 (tr, J=6.8 Hz, 2H), 4.63 (t, J=4.8 Hz, 2H), 3.84 (t, J=4.8 Hz, 2H), 3.48 (t, J=4.8 Hz, 2H), 3.31 (t, J=4.8 Hz, 2H), 3.11 (s, 3H), 1.59 (t, J=6.8 Hz, 3H). 13C NMR (400 MHz, DMSO-d6) δ 153.2, 146.7, 145.1, 142.2, 140.9, 137.7, 135.0, 128.9, 127.4, 126.8, 126.7, 126.5, 126.4, 122.8, 122.2, 121.8, 120.4, 119.9, 119.0, 116.2, 115.5, 110.4, 110.3, 71.3, 69.8, 68.9, 58.1, 51.9, 15.1.
