Application

(S)-BINOL ligand in combination with titanium(IV) isopropoxide, forms (S)-(-)-BINOL-Ti complex, which is an effective chiral catalyst for:

  • asymmetric addition of alkynylzinc to unactivated ketones
  • enantioselective ring-opening reaction of meso-stilbene oxide and cyclohexene oxide with anilines
  • asymmetric aryl transfers from triaryl(tetrahydrofuran)aluminum reagents to a wide variety of ketones
It can also react with zirconium(IV) isopropoxide isopropanol complex to form a chiral Lewis acid catalyst for the facile enantioselective allylation of aldehydes by allyltributyltin.

Precursor to phosphoramidite catalyst employed in a conversion of allylic alcohols to allylic amines.
