Michael reaction between silyl enolates and α,β-unsaturated carbonyl compounds by using a catalytic amount of Lewis base such as lithium alkoxide in DMF proceeds smoothly to afford the corresponding Michael-adducts in good yields with moderate to high diastereoselectivities. This reaction can be reasonably explained by considering an alkoxide anion-initiated autocatalytic process.
Indium-trichloride catalyzed Michael reaction of silyl enol ethers with α,β-unsaturated carbonyl compounds under neat condition

In the presence of a catalytic amount of indium (III) trichloride (InCl3) (20 mol%), ketene silyl enol ethers react quickly with α, β- unsaturated ketones and esters to afford the corresponding Michael adducts in moderate to good yields. Indium(III) trichloride can be recovered and reused without decrease in yields.
Stereoselective Michael additions of titanium "ate" complexes of ketone and ester enolates

The conjugate addition of Ti "ate" complexes of ketone and ester enolates to α,β-unsaturated carbonyl compounds was studied. The reaction was found to be highly regio- and stereoselective. Compared to the lithium enolates, ketone enolate Ti complexes show
