Diastereodivergent asymmetric Michael-alkylation reactions using chiral N,N′-dioxide/metal complexes

A diastereodivergent asymmetric Michael-alkylation reaction between 3-chloro-oxindoles and β,γ-unsaturated-α-ketoesters has been achieved using L-RaPr(2)/Sc(OTf)(3) and L-PrPr(2)/Mg(OTf)(2) metal complexes as catalysts. Both rel-(1R,2S,3R) and rel-(1S,2S,3R) chiral spiro cyclopropane oxindoles were...
