Asymmetric Synthesis of Allenyl Oxindoles and Spirooxindoles by a Catalytic Enantioselective Saucy–Marbet Claisen Rearrangement

Saucy selection: The first catalytic, enantioselective Saucy–Marbet Claisen rearrangement has been achieved. Palladium(II) (R)-binap or tBuphox catalysts L*Pd(SbF6)2 were employed to generate allenyl oxindoles or spirolactones bearing a quaternary center with up to 98 % ee.
