Oxidation of diglycerol to diglycerose using hydrogen peroxide as a clean oxidant

Abstract

The oxidation of diglycerol to diglycerose was developed using hydrogen peroxide as a clean oxidant and cerium bromide as a commercially available catalyst. Several parameters were investigated such as catalyst nature and loading, amount of oxidant, reaction time, solvent and concentration of starting material. This parametric study allows forming diglycerose on the gram scale. With a convenient access to diglycerose, several reactions were investigated such as acetylation and glycosylation in order to provide new biobased platform molecules.
