在KF-Al~2O~3催化下,将芳香醛、5,5-二甲基-1,3-环己二酮及丙二酸亚异丙酯在醇中反应,一锅式合成了一系列的3-芳基-3-(5,5-二甲基-3-羟基-2-环己烯-1-酮-2-基)丙酸酯。通过单晶X射线衍射分析确定了产物的结构,并提出了可能的反应机理。

A series of 3-aryl-3-(5, 5-dimethyl-3-hydroxy-2-cyclohexene-1-one-2- yl) propanoic esters were synthesized by reaction between aromatic aldehydes, 5, 5-dimethyl-1, 3-cyclohexanedione and isopropylidene malonate catalyzed by KF-Al~2O~3 in alcohols. The structure of 4a was determined by X-ray analysis. A possible mechanism for this reaction is postulated.
