1-Aryltetrahydroisoquinolines (1-arylTHIQs) are Important structural motifs in many alkaloids and biologically active compounds. Ligand 2a promotes the enantioselective addition of arylzinc reagents to 3,4-dihydroisoquinoline N-oxide to yield (S)-1-arylTHIQs in 97-99% ee. Pinacol arylboronic esters are the optimal precursors for the arylzinc reagents. This method is applied to the enantioselective synthesis of Solifenacin.

A transition-metal-free strategy to construct C(sp(2))-N bonds using arylboroxines and O-benzoyl hydroxylamines as coupling partners has been developed. This transformation provides a useful method to access various aromatic amines.
