Copper-catalyzed conjugate addition of organomanganese reagents to α, β ethylenic esters easily takes place in THF at 0 °C, in the presence of 3% CuCl and Me3SiCl. Good to moderate yields are obtained from organomanganese reagents prepared from organolithium or organomagnesium compounds.

The conjugate addition of organomagnesium reagents to α, β-ethylenic esters is performed in THF, at room temperature (30 min to 1.5 h), in the presence of CuCl (3%) and Me3SiCl (1.2 eq.). Good yields of 1,4-addition products are obtained according to this very simple procedure.

Kinetic resolution of the N-methyl imines of 3-substituted indanones and 4-substituted tetralones could be accomplished by hydrosilylation with a chiral titanocene catalyst. N-Methyl imines of 4-substituted tetralones were resolved to yield, after hydrolysis of the unreacted starting materials, ketones with high ee's and the amine products with high diastereomeric and enantiomeric purity. The utility of this process was demonstrated in the synthesis of sertraline.
