Applications of Chiral Phosphine-Based Organocatalysts in Catalytic Asymmetric Reactions

Catalytic enantioselective synthesis of quaternary 3,3′-indolyloxindoles by combination of Rh(ii) complexes and chiral phosphines

Rh(ii)/chiral phosphine combined catalysis has been developed for a highly efficient sequential C–H functionalization/asymmetric allylation or Michael addition reaction to afford a diverse range of quaternary 3,3′-indolyloxindole derivatives.
