Enantiodivergent C3-Selective Reduction of Arylvinyl-Substituted 3,5-Dicarbonyl Esters Enabled by Engineered Ketoreductases.
Chiral arylvinyl-substituted 3-hydroxy-5-oxo esters are valuable motifs in pharmaceuticals, yet their enantiocontrolled synthesis remains challenging. Herein, we report a biocatalytic system using ketoreductases (KREDs) for the highly C3-selective reduction of arylvinyl-substituted 3,5-dicarbonyl esters. Through semira...
