Formation of chiral fluoroalkyl products through copper-free enantioselective allylic alkylation catalyzed by an NHC ligand.

David Grassi1, Hailing Li, Alexandre Alexakis.   

Abstract

A valuable Cu-free protocol is reported where an NHC ligand has been employed to form quaternary carbon centers bearing fluoroalkyl units. The results obtained, from this allylic substitution, are better in terms of enantioselectivity and regioselectivity compared to the copper catalyzed system.
