Chiral buildingblocks are valuable intermediates in the syntheses of naturalproducts and pharmaceuticals. A scalable chemoenzymaticroute to chiral diketides has been developed that includes the general synthesis of α-substituted, β-ketoacyl N-acetylcysteamine thioesters followed by a biocatalytic cycle in which a glucose-fueled NADPH-regeneration system drives reductions catalyzed by isolated modular
