Abstract
This paper presents a scalable flow system using immobilized enzymes for flavin-dependent biocatalysis, specifically asymmetric alkene reduction. The system integrates an Old Yellow Enzyme (OYE) and a soluble hydrogenase for H₂-driven FMNH₂ regeneration. H₂ is produced via water electrolysis. The system shows high stability and reusability, achieving >99% conversion of ketoisophorone to levodione, demonstrating versatility and selectivity in reducing various cyclic enones. This electro-driven continuous flow system has significant potential for sustainable fine chemical synthesis.
