Seen to be green: A highly efficient and green method for catalyzing the enantioselective photooxygenation of β‐keto esters with molecular oxygen in the presence of chiral phase‐transfer catalysts has been developed. High yields (up to 93 %) and good enantiomeric excesses (up to 75 %) could be obtained, and a plausible reaction mechanism has been proposed to explain the outcome of the reaction.
