A novel bifunctional photocatalyst combining an aza-BODIPY and a chiral oxazoline has been developed. This photocatalyst enables the asymmetric hydroxylation of β‑ketoesters under an oxygen atmosphere and irradiation with 18-W red LEDs. This procedure offers a convenient and potentially general approach to obtain enantioenriched α-hydroxy-β-dicarbonyl products. The results reported in this manuscript demonstrate the promise of this new organic photocatalyst design and will help expand the application of BODIPY-based chiral photocatalysts.
