Abstract

A green acetic acid-mediated synthesis of kojic acid derivatives through a multicomponent reaction (MCR) has been developed. This new protocol is simple and efficient; it involves a one-pot reaction of equimolar amounts of kojic acid, aromatic aldehydes, and several active methylene compounds at 90°C in 3 h and results in the formation of a wide range of kojic acid derivatives with high yields. Furthermore, the formation of acyclic product when only kojic acid reacted with benzaldehyde under similar reaction conditions has been explored.

醋酸介导的曲酸衍生物合成

摘要

通过多组分反应 (MCR) 开发了一种绿色乙酸介导的曲酸衍生物合成。这个新协议简单而高效；它涉及等摩尔量的曲酸、芳香醛和几种活性亚甲基化合物在 90°C 下在 3 小时内进行一锅反应，并以高产率形成范围广泛的曲酸衍生物。此外，已经探索了在类似反应条件下仅曲酸与苯甲醛反应时无环产物的形成。
