产品说明

应用

Ethyl acetoacetate can be used as a reactant in the synthesis of:

  • Knoevenagel condensation products by reacting with α-alkylideneacetoacetate and aliphatic, aromatic, heteroaromatic aldehydes.
  • Michael adducts, via Michael addition reaction with chalcones and azachalcones in the presence of a base catalyst.
  • Substituted nicotinic acid derivatives by treating with α, β-unsaturated oximes via Michael addition followed by ring closure reaction.

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