  • Diels-Alder reaction with furanics to obtain aromatics
    Patent number: 11384095
    Abstract: The present invention is directed to the preparation of phthalic anhydride compounds and the intermediate phthalide compounds. In particular, the invention is directed to an improved bio-based route from furanic compounds to phthalic anhydride compounds by reacting furfuryl alcohol (i.e. 2-hydroxymethylfuran) or an analogue thereof having a nucleophilic atom on the 2-methyl, with a dienophile comprising an ?,?-unsaturated carbonyl comprising an ??-leaving group. The inventions further involved preparation of phthalic anhydride compounds, phthalic acid compounds and reduction products of the intermediate phthalide compounds.
    Type: Grant
