Title:
SYNTHESIS OF SUBSTITUTED FURANS
Document Type and Number:
WIPO Patent Application WO/2021/016220
Kind Code:
A3
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.
