Carbonyl-protected .beta.-lithio aldehydes and ketones via reductive lithiation. A general preparative method for remarkably versatile homoenolate equivalents
摘要:
A general procedure for producing homoenolate equivalents consists of reductive lithiation, induced by 4,4'-di-tert-butylbiphenylide, of carbonyl-protected beta-(phenylthio) carbonyl compounds prepared in turn by thiophenol addition to enones or the alkylation of silyl enol ethers by alpha-chlorothioethers.
