A method of manufacturing esters of dicarboxyimidolevulinic acid and alkyl trans-4-oxo-2-pentenoate. This method includes two reaction steps, wherein the first step of said two reaction steps is a bromination of alkyl-levulinate, to obtain alkyl-(3 and 5)-bromolevulinate, and the second step of said two reaction steps is a synthesis of esters of dicarboxyimidolevulinic acid and alkyl trans-4-oxo-2-pentenoate, by reacting the alkyl-(3 and 5)-bromolevulinate obtained in said first step with dicarboxyimide anion.
