Early transition metal alkoxide complexes bearing homochiral trialkanolamine ligands

Homochiral trialkanolamine ligands, present in early transition metal complexes, exhibit characteristic features of enantioselective catalysis. Trialkanolamines enable synthesis in enantiopure form and generate thermally- strong tetradentate complexes with early transition metals. Trialkanolamines form a highly-asymmetric environment near transition metals. The three similar O-C-H hydrogen atoms allow chirality initiation in the coordination sphere of the metal.
