| Application: | 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. |
