A General Preparative Method for Carbonyl-Protected γ-Lithioketones via Reductive Lithiation. Synthetic Uses of the Bishomoenolate Equivalents
The mixed cuprates, generated by reductive lithiation of bis(phenylthio)acetals using lithium 4,4'-di-tert-butylbiphenylide (LDBB), followed by addition of cuprous bromide-dimethyl sulfide complex, undergo conjugate addition to enones in the presence of t
