Highly enantioselective Mannich and α-amination reactions have been successfully developed using α-fluorinated aromatic ketones as fluorocarbon nucleophiles in the presence of a bicyclic chiral guanidine (see scheme; Ms=methanesulfonyl). This method is a simple and efficient approach to the construction of fluorinated quaternary stereogenic centers.
