摘要
Preparation of 2,5,6-trihydroxy-3-hexenoic acid and 2,5-dihydroxy-3-pentenoic acid and esters thereof from C6 and C5 sugars in the presence of a Lewis Acid material, wherein the yield of the 2,5,6-trihydroxy-3-hexenoic acid or 2,5-dihydroxy-3-pentenoic acid or esters thereof exceeds 15%. The process including the steps of contacting a saccharide composition including one or more C6 and/or C5 saccharide units with a Lewis Acid material; and recovering 2,5,6-trihydroxy-3-hexenoic acid and/or 2,5-dihydroxy-3-pentenoic acid or the esters thereof.
