应用： 乙酰乙酸乙酯是一种多功能试剂，可用作烷基化、共轭加成和缩合反应的亲核试剂。其中一些应用有： 在乙酰乙酸乙酯的α-碳上进行烷基化，然后水解和脱羧，即可产生各种甲基酮。 在MgCl2 和吡啶存在时，它还能在α-碳上进行酰化，得到合成重要的中间体。 它可以用于与脂族、芳族和杂芳族醛发生Knoevenagel缩合反应，生成α-亚烷基乙酰乙酸酯。 Application： Ethyl acetoacetate is a versatile reagent that can be used as a nucleophile in alkylation, conjugate addition and condensation reactions.Some of its applications are: Alkylation at the α-carbon of ethyl acetoacetate followed by hydrolysis and decarboxylation can afford a variety of methyl ketones. It also undergoes acylation at the α-carbon in the presence of MgCl2 and pyridine to give synthetically important intermediates. It can be used in Knoevenagel condensation with aliphatic, aromatic, and heteroaromatic aldehydes to produce α-alkylideneacetoacetates.
