摘要
Catalytic enantioselective Friedel-Crafts alkylations of indoles and nitroalkenes were carried out by using a new heterotrimetallic Cu/Eu/Cu complex catalyst based on the simple chiral ligand, reduced Schiff base 1, to give the Friedel-Crafts adducts with up to 88% yield and 80% ee. The trimetallic catalyst is air-stable and can be formed insitu by a facile solution self-assembly during the catalytic reaction.
