Asymmetric Reactions Catalyzed by Chiral Tridentate Schiff Base-Metal Complexes

The chiral tridentate Schiff bases, which derived from various chiral amino alcohols and salicylaldehyde derivatives, complexed with metals, such as Ti, Cr, V, Cu, Fe and Al, have shown catalytic ability in many asymmetric reactions. Especially in asymmetric trimethylsilylcyanation of aldehydes, Diels-Alder reaction, aldol reaction, hetro-ene reaction and sulfide oxidation reaction, systematic work has been reported. The development of the work was described in this review, meanwhile, the catalytic activity and enantioselectivity infuenced by the structure of catalyst and reaction condition were also discussed． Contents
