Asymmetric Friedel-Crafts Alkylation of Indoles with Trifluoromethyl Pyruvate Catalyzed by a Dinuclear Zinc Catalyst
A bimetallic cooperative catalysis model has been reported for the asymmetric Friedel-Crafts (F-C) alkylation of indoles with trifluoromethyl pyruvates using Trost’s intramolecular dinuclear zinc complex as the catalyst. This dinuclear zinc catalyst was prepared in situ by reacting the chiral ligand (S,S)-L2b with 2 equiv of ZnEt2. A series of trifluoromethyl alcohol and indole-containing biological compounds were formed in moderate to good yields (up to 95%) with good enantioselectivity (up to 88% enantiomeric excess (ee)) in the presence of 10 mol % catalyst under mild conditions. A synergistic transition state model was proposed to explain the origin of the asymmetric induction.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 52415-29-9, you can also check out more blogs about52415-29-9
