Metalated 2-Alkenylsulfoximines: Reactivity and NMR-Spectroscopic Studies

Enantiomerically pure, metalated 2-Alkenylsulfoximines were used to prepare γ-hydroxyvinylsulfoximines yielding very high diastereomeric excesses. Experiments with epimeric mixtures and NMR-spectroscopic studies of the lithiated intermediates demonstrate their configurational lability as opposed to...

Zusammenfassung:Enantiomerically pure, metalated 2-Alkenylsulfoximines were used to prepare γ-hydroxyvinylsulfoximines yielding very high diastereomeric excesses. Experiments with epimeric mixtures and NMR-spectroscopic studies of the lithiated intermediates demonstrate their configurational lability as opposed to the assumed configurational stability of the titanium compound.
