A new synthetic procedure for the practical synthesis of β-trimethylsiloxyketones from silyl enol ethers and aldehydes has been described which heavily depends on organoaluminum reagent as an effective catalyst.
Enolboronates, new enolates directly accessible from carbonyl compounds, exhibit extraordinary high erythro diastereoselection both with aliphatic and aromatic aldehydes.
