Palladium-catalyzed cross-coupling reactions of flavone triflates 2a–c, 4a with tetravinyltin give the corresponding vinylflavones 5a–d, whereas reactions with benzophenone imine, followed by cleavage, afford the corresponding aminoflavone.
黄酮三氟甲磺酸2a-c,4a与四乙烯基锡的钯催化交叉偶联反应得到相应的乙烯基黄酮5a - d,而与二苯甲酮亚胺反应,然后裂解,得到相应的氨基黄酮。
