Vue d’ensemble

(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.
