Generation of Enolates from α,β-Epoxy Sulfoxides with Lithium Dimethylcuprate: A Novel Synthesis of Aldols and Some Trial to Trap the Enolates

Enolates were generated from α,β-epoxy sulfoxides using lithium dimethylcuprate as an electron-transfer reagent. The enolates were trapped with several electrophiles, in which aldehydes reacted with the generated enolates giving aldols in good yields with high regioselectivity.
