The feasibility of a previously established method based on ozonolysis and hydrogenation reactions for the production of 9-hydroxynonanoic acid from oleic acid has been demonstrated. Metal catalyzed lactonization conditions have been used to convert 9-hydroxynonanoic acid into 1,11-dioxacycloicosane-2,12-dione, which is
