    Abstract: In recent years, levulinic acid has been considered as a key biobased platform compound and attracted wide attention, which can be utilized in the synthesis of many high value-added chemicals. Among them, levulinates, as a class of important chemical products, can be used in alternative fuels, edible spices, plasticizers and other fields, especially as alternative fuels, which provides a feasible reference scheme for sustainable development. In this paper, the recent research progress on the catalytic synthesis of levulinates in the field of biomass conversion was reviewed. The reaction performances and related mechanisms were introduced involving in several approaches, such as the esterification of levulinic acid, the alcoholysis of furfuryl alcohol, the conversion of monosaccharides and cellulosic materials, respectively. The synthesis of levulinates was summarized and prospected.
