Application
- Ethyl 2-methylacetoacetate is used as a substrate in the rhenium-catalyzed synthesis of multisubstituted aromatic compounds.
- It can be employed in the synthesis of coumarin derivatives via Pechmann condensation.
- It undergoes dehydration to yield conjugated alkynyl and allenyl esters.
- It is also used in the total synthesis of chlorotonil A, yangjinhualine A, (+)- and (−)-saudin.

The co-immobilization of ketoreductase (KRED) and glucose dehydrogenase (GDH) on highly cross-linked agarose (sepharose) was studied. Immobilization of these two enzymes was performed via affinity interaction between His-tagged enzymes (six histidine residues on the N-terminus of the protein) and agarose
