Linear mono- and dialkyl ethers of furan-2,5-dimethanol (FDM) and/or (tetrahydrofuran-2,5-diyl)dimethanol (bHMTHF), 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 with a permittivity (∈) >8, at a temperature ranging from about −25° C. to about 100° C., with either a) an unhindered Brønsted base with a ΔpKa≧15 relative to the hydroxyl groups of the FDM or bHMTHF, or b) a hindered Brønsted base having minimum pKa of about 16 and a nucleophile.
