三氟甲磺酸铜(II)可有效催化乙腈中醛、β-酮酯和脲的三组分缩合反应，以高产率生成相应的3,4-二氢嘧啶-2(1H)-酮。该催化剂表现出显着的可重复使用活性。 (C) 2003 Elsevier Science Ltd. 保留所有权利。
Copper(II) triflate catalyzes efficiently the three-component condensation reaction of an aldehyde, beta-ketoester and urea in acetonitrile to afford the corresponding 3,4-dihydropyrimidin-2(1H)-ones in high yields. The catalyst exhibited remarkable reusable activity. (C) 2003 Elsevier Science Ltd. All rights reserved.
