Triple A: The catalytic asymmetric allylic alkylation (AAA) of 3‐aryloxindoles with allylidene dipivalate is described. This reaction affords stable, synthetically useful enol pivalates in high yield and with excellent regio‐ and enantioselectivity. A broad range of substrates is tolerated, including unprotected and 3‐heteroaryl nucleophiles.
