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.
