Ethyl 2-oxocyclopentanecarboxylate Chemical Properties,Usage,Production
Description
Ethyl 2-oxocyclopentanecarboxylate (EOCPC) is a multifunctional organic reagent that can be used as a pharmaceutical intermediate or raw material for chemical synthesis. EOCPC reacts with kaolinite to prepare intercalation compounds. It also participates in Michael reactions and diazonium transfer reactions for the preparation of other active ingredients.
Chemical Properties
clear colourless to pale yellow liquid
Uses
Pharmaceutical intermediate.
Uses
Ethyl 2-oxocyclopentanecarboxylate was used in stereoselective synthesis of (±)-cis,cis-spiro[4.4]nonane-1,6-diol. It was also used in the synthesis of tanikolide.
