Enantioselective catalytic oxidations of nonfunctionalized alkenes (Equation (a), X = H, alkyl, aryl) remained a challenge long after Sharpless and co‐workers developed the enantioselective epoxidation of allyl alcohols (Equation (a), X = OH) ten years ago. Designer catalysts based on porphyrins recently brought new progress, while poly‐ L ‐leucine proved attractive as catalyst for the epoxidation of diverse chalcones with H 2 O 2 /NaOH in up to 92% ee.
