Enantioselective Friedel−Crafts Alkylations Catalyzed by Bis(oxazolinyl)pyridine−Scandium(III) Triflate Complexes

The enantioselective Friedel−Crafts addition of a variety of indoles catalyzed by bis(oxazolinyl)pyridine−scandium(III) triflate complexes (Sc(III)−pybox) was accomplished utilizing a series of β-substituted α,β-unsaturated phosphonates and α,β-unsaturated 2-acyl imidazoles. The acyl phosphonate pro...
