Diastereoisomerically selective enantiomerically pure titanium complexes of Salan ligands: Synthesis, structure, and preliminary activity studies
The degree of diastereoselectivity in the wrapping of four new chiral Salan ligands to form chiral-at-metal titanium complexes ranged from mild to perfect as a function of the ligands' N substituents; the enantiomerically pure complexes catalyzed the addition of diethyl zinc to benzaldehyde in 73-76% enantiomeric excess.
