Paeonol is a major phenolic component isolated from Moutan Cortex, a traditional Chinese medicine. An efficient synthesis of paeonol derivatives linked to a 1,2,3-triazole moiety using a 1,3-dipolar Huisgen-cycloaddition reaction is described. The paeonol derivatives are regioselectively obtained in good yields under mild conditions using Cu(OAc)2·H2O/sodium ascorbate as a catalyst system, and t-BuOH/H2O
丹皮酚是从中药牡丹皮中分离出的主要酚类成分。描述了使用 1,3-偶极 Huisgen-环加成反应连接到 1,2,3-三唑部分的丹皮酚衍生物的有效合成。以Cu(OAc)2·H2O/抗坏血酸钠为催化剂体系,t-BuOH/H2O (1:1, v/v)为共溶剂,在温和条件下以高产率区域选择性地获得丹皮酚衍生物。
