Abstract The synthesis of (E)-3-substituted styrylquinoxalin-2(1H)-ones was achieved by the reaction of 3-methylquinoxalinone and aromatic aldehydes using FeCl3 as a catalyst in toluene under microwave irradiation. The protocol is endowed with milder reaction conditions, high yields of product, and easy workup procedures.
摘要 (E) -3-取代的styrylquinoxalin-2(1 H )-ones的合成是通过3-甲基喹喔啉酮和芳香醛在甲苯中以FeCl 3为催化剂在微波辐射下反应实现的。该方案具有反应条件温和、产物收率高、后处理简单等特点。
