Description
- 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[1]enantioselective ring-opening reaction of meso-stilbene oxide and cyclohexene oxide with anilines[2]asymmetric aryl transfers from triaryl(tetrahydrofuran)aluminum reagents to a wide variety of ketones[3]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.[4]
