  • Publication number: 20250011265
    Abstract: A chemoenzymatic method of producing a polyhydroxybenzene includes contacting glucose with one or more biocatalysts under conditions suitable for the formation of D-glucodialdose; and thermally treating D-glucodialdose in the presence of a dehydration catalyst under conditions suitable for the formation of the polyhydroxybenzene. A chemoenzymatic method of producing 1,2,3,4-tetrahydroxybenzene includes contacting glucose with a mutated copper radical oxidase and catalase under conditions suitable for the formation of D-glucodialdose; and subjecting D-glucodialdose and a dehydration catalyst to temperatures ranging from about 40° C. to about 100° C. suitable for the formation of 1,2,3,4-tetrahydroxybenzene.
