Abstract A convenient and facile method for Michael addition of methylene active compounds to chalcones has been developed by using 1,8-diazabicyclo [5.4.0]undec-7-ene- derived task-specific ionic liquids as reaction medium in the absence of any catalyst. This protocol could afford the Michael adducts in good to excellent yields in a short time, the workup is very simple, and the ionic liquid could
摘要 使用 1,8-二氮杂双环 [5.4.0] undec-7-ene 衍生的任务特异性离子液体作为反应介质,在不存在任何物质的情况下,开发了一种将亚甲基活性化合物迈克尔加成到查耳酮的简便方法。催化剂。该方案可以在短时间内提供高产率的迈克尔加合物,后处理非常简单,离子液体可以重复使用六次而不会显着损失活性。图形概要
