Organocatalytic Conjugate Additions of Acetylacetone to 3-Ylideneoxindoles: A Direct Access to Highly Enantioenriched Oxindole Derivatives

[摘要]：A highly enantioselective organocatalytic conjugate addition of acetylacetone to 3-ylideneoxindoles is described. This method provides polysubstituted oxindoles in good to excellent enantioselectivities and high isolated yields.
