应用

Ethyl acetoacetate can be used as a reactant to synthesize:
  • 7-hydroxycoumarin derivatives via Pechmann condensation reaction with 1,3-dihydroxybenzene in the presence of acid catalysts.
  • 2,6-disubstituted piperidine alkaloid, (−)-pinidinone via stereoselective α-aminoallylation followed by Grubbs′ olefin cross-metathesis reaction.
  • Michael addition products via Michael addition reaction with chalcones and azachalcones in the presence of a base catalyst.
  • α, β-unsaturated carbonyl compounds via Knoevenagel condensation reaction with glyceraldehyde acetonide in the presence of a base catalyst.

It can be also utilized as a reactant in the transesterification and asymmetric hydrogenation reactions to produce valuable products.
