Triple A: The catalytic asymmetricallylicalkylation (AAA) of 3‐aryloxindoles with allylidenedipivalate is described. This reaction affords stable, synthetically usefulenolpivalates in high yield and with excellent regio‐ and enantioselectivity. A broad range of substrates is tolerated, including unprotected and 3‐heteroaryl nucleophiles.
