  complex of copper(II) trifluoromethanesulfonate with chiral isopropyl bis(oxazoline) ligand (i-Pr-Box) was immobilized on accessible and inexpensive Merrifield resin according to a “click” procedure. The resulting catalyst showed high efficiency and recyclability in the asymmetric Friedel–Crafts alkylation of indole and its derivatives. The catalyst can be recycled five times without appreciable loss in

  The chiral dicationic Pd complexes, bearing sterically demanding diphosphine ligands as Lewis acid catalysts, are shown to catalyze the asymmetric Friedel–Crafts (F–C) alkylations of indoles and pyrroles with β,γ-unsaturated α-ketoesters, to provide the F–C alkylation products with benzylic stereocenters in high yields and enantioselectivities. The reactive chelated structure, formed by the chiral dicationic

  exchange of the metal ion from Zr(IV) to Fe(III) leads to a switch in the enantioselectivity of binary acid-catalyzed conjugate hydride reductions. In the presence of Hantzsch ester, γ-indolyl β,γ-unsaturated α-keto esters could be reduced to the desired (S)- or (R)-products, respectively, with good to excellent enantioselectivity (up to 98% ee).

  金属离子从 Zr(IV) 到 Fe(III) 的交换导致二元酸催化的共轭氢化物还原的对映选择性发生变化。在 Hantzsch 酯存在下，γ-吲哚基 β,γ-不饱和 α-酮酯可以分别还原为所需的 ( S )- 或 ( R )- 产物，具有良好至优异的对映选择性（高达 98% ee） .

  Enantioselective Friedel-Crafts alkylation reactions of indoles with beta,gamma-unsaturated alpha-ketoesters catalyzed by novel chiral C-2-symmetric squaramide-linked bisoxazoline-Zn(OTf)(2) complexes were investigated. The corresponding indole ketoesters were obtained in good to excellent yields (up to 98%) and with high enantioselectivities (up to 94% ee). This is the first report on the use of chiral squaramide-linked bisoxazoline SQBOX in a catalytic enanitioselective Friedel-Crafts alkylation reaction. (C) 2014 Elsevier Ltd. All rights reserved.
