Chiral Phosphoric Acid Catalyzed Enantioselective Friedel–Crafts Alkylation of Indoles with Nitroalkenes: Cooperative Effect of 3 Å Molecular Sieves

Crafty catalysts: Friedel–Crafts alkylation of indoles with nitroalkenes proceeded in the presence of phosphoric acid 1 and 3 Å molecular sieves to give Friedel–Crafts adducts with excellent enantioselectivities (see scheme).
