of 5-hydroxymethylfurfural (HMF)-derived humins were captured, revealing multiple elementary reactions such as etherification, esterification, aldolcondensation, and acetalization. Through humin characterization, it was found out that the aldolcondensation moiety between aldehyde group and levulinic acid is critical to justify the characteristic IR peaks (1620 and 1710 cm-1 ) and aromatic fragments

Methods for preparing 1) a sugar-derived ester, 2) a glycol generated from reduction of the ester, and 3) polymers fabricated from polycondensation of the ester or glycol with various diamines and dicarboxylic acids are described. In particular, the ester is levulinic 5-methyl-2-furfural (LMF), the acylation product of hydroxymethyl-furfural (HMF) and either a levulinyl halide or levulinic acid. Each of the embodiments for the synthesis is highly selective for the product and can be executed under relatively mild reaction conditions.
