  A unique binary chiral phosphoric acid 1a/MgF2 catalyst that enables effective catalysis of asymmetric Friedel−Crafts reactions of phenols with up to 82% yield and >99% ee is presented. A dramatic synergistic effect has been observed in the combinations of two types of acids, wherein a highly active binary-acid catalyst can be generated from two individually inert acids.

  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.

  The simple and cheap chiral catalyst, heteroarylidene-tethered Ph-bis(oxazoline)-Cu(OTf)(2), can efficiently catalyze the asymmetric F-C alkylation of indoles and pyrrole with beta,gamma-unsaturated alpha-ketoesters. The 3-indolyl adducts were obtained in up to >99% ee. Moreover, the 2-pyrrolyl adducts were achieved in up to 92% ee for the first time.
