Chiral Ligands

Chiral ligand 1 is used for enantioselective addition of Grignard reagents to ketones which affords tertiary alcohols with high optical yields¹⁾. Furthermore, a variety of titanium complexes may be prepared from 1, and the titanium complexes are used for asymmetric allylation reactions²⁾, asymmetric alkylation reactions³⁾, asymmetric iodocarbocyclization reactions⁴⁾, and asymmetric Diels-Alder reactions⁵⁾ etc.
