Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biofuels undergo oxidative degradation, which reduces their storage stability and efficiency, hindering their large‐scale adoption and integration into the global energy matrix. To address this issue, we synthesized and characterized four novel quinolinone–chalcone derivatives (substituted with Br, Cl, OCH3 and OCH2CH3) as potential ...

Biotechnology and Bioengineering, Volume 122, Issue 5, Page 1296-1304, May 2025.Here, an efficient system for synthesizing high‐value polyphenol hetero‐di‐C‐glycosides with two distinct C‐glycosyl residues was established using a two‐step glycosylation catalyzed by C‐glycosyltransferase in one pot. The desired C‐β‐galactosyl‐C‐β‐glucosyl and C‐β‐glucosyl‐C‐β‐xylosyl phloretin were obtained at concentrations of 0.6 and 6 g/L ...
