実験手順
4-Hydroxybenzaldehyde (1.10 g, 9.17 mmol), cesium carbonate (3.49 g, 10.70 mmol) and 53B (2.70 g, 7.64 mmol) were mixed with DMF (80 mL). The mixture was stirred at 110° C. for 18 h and then cooled to RT. The solids were filtered off and the filtrate was evaporated. The residue was treated with methanol and the formed solid was collected by filtration. Drying under vacuum afforded 1.8 g (62%) of 68A as a beige solid. 1H NMR (500 MHz, DMSO-d6): δ 3.85 (s, 3H), 4.13 (dd, 1H), 4.57 (dd, 1H), 4.65 (dd, 1H), 5.12 (dd, 1H), 5.29 (m, 1H), 7.10 (d, 2H), 7.16 (d, 2H), 7.90 (d, 2H), 8.00 (d, 2H), 9.90 (s, 1H), MS (APCI+) m/z 380 [M+H]+.
