With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15832-09-4,6-Methoxy-3(2H)-benzofuranone,as a common compound, the synthetic route is as follows.
To a solution of 6-methoxybenzofuran-3(2H)-one (58?mg, 0.354?mmol) in MeOH (5?mL) were added an aqueous solution of KOH (50%, 0.30?mL) and 3,4-dimethoxybenzaldehyde (59?mg, 0.354?mmol), and the mixture was stirred at room temperature for 2?h. The solid was then filtered, washed with cold MeOH and dried. The crude product was recrystallized from MeOH to afford 34 (25?mg, 23%) as a yellow solid. 1H NMR (CDCl3) delta 7.72 (d, 1H, J?=?8.3?Hz), 7.51 (d, 1H, J?=?1.9?Hz), 7.48 (dd, 1H, J1?=?8.3?Hz, J2?=?1.9?Hz), 6.94 (d, 1H, J?=?8.3?Hz), 6.80 (s, 1H), 6.77 (dd, 1H, J1?=?8.3?Hz, J2?=?2.1?Hz), 6.76 (s, 1H), 3.99 (s, 3H), 3.95 (s, 3H), 3.94 (s, 3H). 13C NMR (CDCl3) delta 183.0, 168.4, 167.4, 150.8, 149.2, 147.0, 126.0, 125.9, 125.6, 115.3, 113.9, 112.6, 112.2, 111.4, 96.8, 56.3, 56.2, 56.2. IR (ATR) upsilon 1596, 1516, 1442, 1424, 1292, 1283, 1261, 1169, 1145, 1122, 1091, 1043, 1015, 949, 896, 862, 835, 816, 771, 700?cm-1. HRMS (ESI) calc. for C18H17O5 [M + H]+ 313.1071, found 313.1065.
15832-09-4 6-Methoxy-3(2H)-benzofuranone 585368, abenzofuran compound, is more and more widely used in various.
