摘要:

发展了一种以碳酸钾为碱,在温和条件下,通过1,2-联烯酮与丙酮二羧酸二乙酯的串联反应高效合成取代2-羟基间苯二羧酸二乙酯类化合物的新方法。 在最优条件下,以73%~85%的收率成功合成了一系列的目标产物。 从机理上而言,该方法涉及了联烯酮与活泼亚甲基化合物的共轭Michael加成和酮的分子内羟醛缩合两个反应的串联组合。 与文献方法相比,该方法还具有简单的起始原料,极高的反应产率和方便的处理过程等优点。

Abstract:

A novel methodology for the synthesis of 2-hydroxyisophthalates through cascade reactions of 1,2-allenic ketones with ethyl acetonedicarboxylate using K2CO3 as the promoter under extremely mild conditions has been developed. Under optimal reaction conditions, a series of 2-hydroxyisophthalates derivatives were obtained with 73%~85% yield. The formation of the title compounds involves firstly a Michael addition of active methylene compounds and allenic ketone followed by its intramolecular condensation. Notable features of this protocol include simple starting materials, high yield, and easiness of handling.
