The catalytic property of Cu(II) Schiff-base complex in an efficient synthesis of 1,8-dioxodecahydroacridines
was investigated. The one-pot three component reaction of dimedone, aromatic aldehydes and aromatic amines or
ammonium acetate in water afforded the corresponding 1,8-dioxodecahydroacridines with excellent yields. This reaction
was carried out in the presence of 1 mol% of catalysts at room temperature. The reusability of the catalysts was
demonstrated by a five-run test without loss of its activity. Also, this catalyst possesses several advantages including mild
reaction conditions, lower catalytic loading, shorter reaction times, high yield of the products, inexpensive and cleaner
(Green chemistry) reactions.
研究了 Cu(II) 希夫碱配合物在高效合成 1,8-二氧代十氢
吖啶中的催化特性。在
水中进行
二甲基酮、芳香醛和芳香胺或
醋酸铵的一锅三组分反应,可以得到相应的 1,8-二氧代十氢
吖啶,且收率极高。该反应是在 1 摩尔%的催化剂存在下于室温下进行的。催化剂的可重复使用性通过五次运行测试得到了证明,其活性没有降低。此外,这种催化剂还具有多种优点,包括反应条件温和、催化负载较低、反应时间较短、产物收率高、成本低廉以及反应更清洁(绿色
