Palladium‐Catalyzed Asymmetric Allylic Alkylation of 3‐Aryloxindoles with Allylidene Dipivalate: A Useful Enol Pivalate Product

Abstract

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.
