Abstract

Abstract α-Lithiosulfinyl carbanions react either intermolecularly, after transmetalation into an organocopper derivative in an SN 2-type process, with zinc carbenoids, or intramolecularly by higher-order zincates through a tandem zinc homologation–β- elimination reaction into the corresponding alkenes. α, α-and α, β-Disubstituted alkenes can also be produced through these two methodologies.(© Wiley-VCH Verlag GmbH & Co. ...
