Enantioselective inhibition of reverse transcriptase (RT) of HIV-1 by non-racemic indole-based trifluoropropanoates developed by asymmetric catalysis using recyclable organocatalysts
Indoles, and pyrroles, and furans, oh my! Chiral phosphoric acidcatalyzed Friedel–Crafts alkylation of indoles with 3,3,3‐trifluoropyruvate gave the corresponding adducts in excellent yields with high enantioselectivities. Electron‐deficient indoles, in particular, exhibited excellent enantioselectivities.

A mild and efficient catalyst system for asymmetric Friedel-Crafts alkylation of indoles with trifluoropyruvates was reported. The chiral ligands took the advantages of both the proline and the binaphthyl moieties, and the in situ prepared Cu(II) catalyst showed good substrate tolerance in the reactions. Indoles bearing different substituents could be tolerated, and the desired products could be obtained
