| Abstract: | A new chiral ligand was prepared in a convenient two-step procedure starting from an asymmetric diamination reaction. Subsequent treatment of the resulting osmaimidazolidine with a phenyl Grignard reagent and titanium tetra(iso-propoxide) furnished a complex that catalyses asymmetric dialkylzinc additions to aromatic aldehydes. |
