Nowadays, the spotlight is on the use of heterogeneous catalysts to yield hydrogenation and hydrogenolysis derived products. In this sense, Pd supported on carbon, alumina, and silica-alumina can be used to obtain a variety of products via hydrogenation (i.e. dihydrolevoglucosenone and levoglucosanol), and hydrogenolysis (i.e. tetrahydrofurandimethanol (THFDM) and 1,6-hexanediol), tuning the selectivity by simply changing reaction conditions. More recently, Pd and Pt supported on zirconium oxide proved to be efficient catalysts to obtain either dihydrolevoglucosenone or levoglucosanol, respectively, under mild reaction conditions, taking advantage of the different selectivity of these metals towards the hydrogenation of specific functional features. In recent times, Levoglucosenone has also been proven to be an interesting Michael acceptor towards the high regio- and stereoselective formation of various building-blocks via a photocatalysed radical addition mediated by tetra-n-butylammonium decatungstate.
