    Resum:
    © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim We have developed the first catalytic asymmetric preparation of sterically hindered tertiary α-aryl oxindoles via enantioselective palladium-catalyzed decarboxylative protonation of the corresponding α-aryl-β-amido allyl esters. The reaction occurs under very mild conditions and in short reaction times, providing excellent yields and promising enantioselectivities (ee's up to 78%). We have also performed an experimental investigation of the reaction mechanism and employed theoretical calculations to understand the nature of the enantioselectivity-determining step. (Figure presented.).
