Abstract
Stereocontrolled addition of organocuprate reagents to γ-alkoxy-α,β-unsaturated esters can be done in one- and two-directional modes with excellent 1,2-induction. Enolate hydroxylations proceed with high diastereoselectivity affording acyclic chains with three to five contiguous stereogenic centers of the propionate and phenylpropionate triad types.
