【摘要】 在微波辐射下,以酸性离子液体甲基咪唑丙磺酸-三氟乙酸为催化剂,利用一锅法由乙酰香豆素、氨基硫脲和α-溴代芳乙酮三组分反应合成了系列3-{1-[2-(4-芳基噻唑-2-基)亚肼基]乙基}香豆素,反应时间短,操作简便,收率高(85%～95%),催化剂可回收循环使用,对环境友好.更多还原

【Abstract】 A series of 3-{1-[2-(4-arylthiazol-2-yl)hydrazono]ethyl}-2H-chromen-2-ones were synthesized with 85%～95% yields via the one-pot three-component reactions of acetyl coumarins,thiosemicarbazide and phenacyl bromide catalyzed by acidic ionic liquid under microwave irradiation.This method provides several advantages such as high yields,easy work-up and environmental friendly,and the catalyst can be recycled.更多还原
