摘　　要：研磨条件下,以SbCl3为催化剂有效的促进了丙二酸亚异丙酯与芳香醛之间的Knovegenel缩合反应,与其它方法相比,主要优点在于反应条件温和,反应速度快,收率高,为Knovegenel缩合反应找到了一条有效途径。The Knovegenel condensation reaction between Meldrum＇ acid and aromatic aldehydes by utilizing antimony trichloride （ SbCl3 ） as a mild catalyst under grinding was described. Compared with the former reaction methods, the present protocol offered several advantages including mild reaction and neutral condition, rapid reaction speed and good yields. An effective method was found for the Knovegenel condensation reaction.
