一般描述
丙二酸二乙酯是丙二酸的二乙酯形式。它广泛用于将丙二酸官能团引入分子的多功能合成砌块。使用氯化镁和三乙胺对丙二酸二乙酯进行酰化已有报道。通过K2CO3催化的丙二酸二乙酯与各种取代形式的1,2-联烯酮的1,4加成反应，生成多官能化的β,γ-不饱和烯酮。
应用
利用沸石催化剂（通过在Nax和CSNax沸石上接枝氨基得到），使用丙二酸二乙酯对微反应器中的Knoevenagel缩合反应进行研究。它可以通过碱催化与苯甲醛进行Knoevenagel缩合，以合成二亚苄基丙二酸酯。它可用于合成α-芳基丙二酸酯。

The K2CO3 (10 mol %)-catalyzed 1,4-addition reaction of diethyl malonate with various substituted 1,2-allenic ketones leading to polyfunctionalized beta,gamma-unsaturated enones 3 or 4 was studied. With 3-unsubstituted 1-substituted-1,2-allenyl ketones, the highly selective formation of beta,gamma-unsaturated enones 4 was observed; with
