1,3-Dicarbonyl compounds chiral metal complexes

In a similar manner, asymmetric carbonyl olefination of meso-dicarbonyl compounds was extended to metallic arene or diene complexes [37], such as // -diene Fe or // -arene Cr complexes, to form planar complexes with high enantiomeric bias (Scheme 7.8). Since both complexation and decomplexation of these optically active compounds occur readily, these olefinic complexes are effective as stereocontrollers due to the presence of bulky metal tricarbonyl groups, and serve as useful reactants for obtaining optically active compounds of central chirality by appropriate chemical transformation.
