International audience; [1,4]-additions of various nucleophiles such as lithiated carbamates, alkoxides or ester enolates onto enantiopure alkylidene bis-sulfoxides proceed with high diastereoselectivity. The oxidation of the resulting carbanions wit

In the first part of the lecture, we will discuss the one-pot preparation of chiral homoallylic alcohol and amine derivatives by a copper-catalyzed four-component reaction. In this process, three new carbon-carbon bonds as well as a quaternary and a

α-Lithiosulfinyl carbanions react either intermolecularly, after transmetalation into an organocopper derivative in an SN2-type process, with zinc carbenoids, or intramolecularly by higher-order zincates through a tandem zinc homologation–β-elimi
