Description

Ethyl cyclopentanone-2-carboxylate (ECPC) is a chemical compound that can be synthesized from picolinic acid, β-amino acid, and methyl ketones. It is a bifunctional molecule that has been shown to have the ability to activate methylene groups. ECPC has been used in the synthesis of β-amino esters and ethyl esters. This compound can also react with hydrogen fluoride and trifluoroacetic acid to form ethyl cyclopentanone-2-carboxylate trifluoroacetate (ECPCT). ECPC has been found to undergo an aldol cyclization reaction when exposed to hydrogen ions in the presence of a base. The activation energies for this reaction are 19.6 kJ/mol for the first step and 23.5 kJ/mol for the second step.
