설명

애플리케이션

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.
