Abstract
Furan carboxylic acids are promising biobased building blocks in pharmaceutical and polymer industries. In this work, dual-enzyme cascade systems composed of galactose oxidase (GOase) and alcohol dehydrogenases (ADHs) were constructed for controlled synthesis of 5-formyl-2-furancarboxylic acid (FFCA) and 2,5-furandicarboxylic acid (FDCA) from 5-hydroxymethylfurfural (HMF), based on the catalytic promiscuity of ADHs. The byproduct H 2 O 2 produced in GOase-catalyzed oxidation of HMF to 2,5-diformylfuran (DFF) was used for horseradish peroxidase (HRP)-mediated regeneration of the oxidized nicotinamide cofactors for subsequent oxidation of DFF promoted by an ADH, thus implementing H 2 O 2 internal recycling. The desired products FFCA and FDCA were obtained with the yields of more than 95%.
This study developed a one-pot enzyme cascade for controlled synthesis of furan carboxylic acids from 5-hydroxymethylfurfural, achieving over 95% yields and implementing H2O2 internal recycling.
