Abstract: A method is provided of preparing a compound of formula II: where: R1 and R2 are independently selected from —CH2OR′, —CHO, —COOR′ and —H, provided that R1 and R2 are not both —H; and R′ is selected from —H and C1-6 hydrocarbyl groups, from a compound of formula I: the compounds of formulas I and II being optionally in the form of a salt. The method comprises dehydrating the compound of formula I at: a pH in the range of from 0 to 6 or 8 to 11.5; and a temperature in the range of from 10 to 80° C. The method is particularly useful for synthesizing substituted furans from compounds derived from sugars.
