Ethyl 2-oxocyclohexanecarboxylate Chemical Properties,Usage,Production

Chemical Properties

Clear colorless to pale yellow liquid

Uses

Ethyl 2-oxocyclohexanecarboxylate is used to produce other chemicals. For example, it can react with 4-methyl-aniline to get 2-oxo-cyclohexanecarboxylic acid p-toluidide. The reaction occurs with reagent DMAP

Uses

Ethyl 2-Oxocyclohexanecarboxylate is used in biocatalysis.

Reactions

The reaction of ethyl 2-oxo cyclohexane carboxylate (I) with phenyl vinyl sulphoxide (II) and sodium hydride followed by pyrolysis of the resulting phenyl sulphonyl ethyl compound (III) gives the 1-vinyl compound (IV).
Baeyer-Villiger oxidation of methyl 3- and 4-oxocyclohexanecarboxylates gave the expected hexanolides, whereas ethyl 2-oxocyclohexanecarboxylate(I) gave 5-ethoxyoxalylpentanoic acid by way of ethyl 1-hydroxy-2-oxocyclohexanecarboxylate, formed by epoxidation of the enol form of (I)[1-2].
