314 mg | With sodium tetrahydroborate; at 20.0℃; for 5.0h; | General procedure: To a mixture of a4-formylbenzenboronic acid (1a, 375 mg, 2.50 mmol), pinacol (355 mg, 3.00 mmol) and anhydrous magnesium sulfate (625 mg, 5.00 mmol), methanol was added (12.50 mL). The mixture was stirred at room temperature for 6 h. After the reaction was completed, the crude solution was filtered, and then sodium borohydride (47 mg, 1.25 mmol) was added to the filtrate. Afterwards, the reaction mixture was stirred for an additional 5 h. Once the reaction was completed, the reaction mixture was filtered and the filtrate was concentrated in vacuo to give the desired product 2a as a white solid (m.p. 75-77 C) in88% yield (513 mg). 1H-NMR (CD3OD-d4) delta ppm 7.71 (d, J = 8.0 Hz, 2H), 7.35 (d, J = 7.8 Hz, 2H),4.62 (s, 2H), 1.34 (s, 12H); 13C-NMR (CD3OD-d4) delta ppm 146.23, 135.93, 127.26, 85.19, 65.24, 25.34;11B-NMR (CDCl3) delta ppm 34.82. |
