title: Asymmetric Organocatalytic Wittig [2,3]-Rearrangement of Oxindoles.
abstract: A highly enantioselective organocatalytic [2,3]-rearrangement of oxindole derivatives is presented. The reaction was catalyzed by squaramide, and this provides access to 3-hydroxy 3-substituted oxindoles in high enantiomeric purities.
