Publication number: 20240131499Abstract: Organocatalysts can be engineered to mimic biological enzymes for use in a variety of industrially relevant chemical reactions. The organocatalyst comprises a chemical catalyst that is made by imidation of an amine-containing compound to form an N-substituted maleimide and appending the N-substituted maleimide on a furan-containing compound by Diels-Alder reaction and hydrogenation. The N-substituted maleimide may also be made by reacting a protected maleimide and compound containing a primary alkyl halide moiety. The organocatalysts are engineered to append chemical functionalities of amino acids such as glutamic acid for catalyzing hydrolysis of lactose.
