摘要:Dicarbamates of the reduction products of 2-hydroxymethyl-5-furfural (HMF) and a method of preparing the same are described. The method involves reacting a mixture of an isohexide and a cynate salt in a non-aqueous solvent, with a miscible acid having a pKa of about 3.7 or less. The dicarbamates of HMF-reduction products can serve as precursor materials from which various derivative compounds can be synthesized.

摘要:Linear mono- and dialkyl ethers of furan-2,5-dimethanol (FDM) and/or 2,5-bis(hydroxymethyl)tetrahydrofuran (bH-MTHF), methods for their preparation, and derivative chemical compounds thereof are described. In general, the synthesis process entails a reaction of FDM or bHMTHFs in a polar aprotic organic solvent having a permittivity ( )>8, at a temperature ranging from about −25 C to about 100 C, with either a) an unhindered Brnsted base with a pKa?15 or b) a hindered Brnsted base having minimum pKa of about 16, and a nucleophile.
