Direct conversion of inexpensive fructose into value-added furanic chemicals via chemobiocatalytic cascades is a highly attractive yet challenging task due to the incompatibility issues between chemo- and biocatalysts. Among issues, solvent crucial make two worlds catalysts work well in one pot. In this work, we present an enzyme-friendly natural deep eutectic (NADES)-based medium for one-pot valorization valuable furanics 5-hydroxymethylfurfural (HMF). HMF was obtained with approximately 40% yield 64% selectivity within 1.5 h under 150 °C 15 wt % NADES (choline chloride/oxalic acid, 1:1, mol/mol) aqueous solution. significantly improved 91% by applying vol methyl isobutyl ketone/NADES biphasic medium. A NADES/unreacted recycle process designed improve both overall (77%) (72%). The NADES-based benign toward various biocatalysts such as alcohol aldehyde dehydrogenases, acyltransferase, ω-transaminase, evidenced good yields (86–97%) desired products subsequent biotransformations. Specifically, 2,5-bis(hydroxymethyl)furan from 41% isolated gram-scale synthesis. This may lay foundation sustainable manufacture high-value biomass.
