N-Tosyl allylic sulfoximines undergo rearrangement to allyl sulfinimidic acid esters in the presence of bidentate chiral ligands while N-Cbz allylic sulfoximines give opticallyactive N-Cbz protected γ-amino-enones.
Fe-Catalyzed Three-Component Coupling Reaction of α,β,γ,δ-Unsaturated Carbonyl Compounds and Conjugate Dienes with Alkylsilyl Peroxides and Nucleophiles
An Fe(OTf)2-catalyzed three-component coupling reaction of α,β,γ,δ-unsaturated carbonylcompounds with alkylsilyl peroxides in the presence of certain heteronucleophiles (ROH and indole) is realized under mild reaction conditions. A variety of α,β,γ,δ-diene carbonyl substrates with different substituents were successfully employable via combination with several different alkylsilyl peroxides. This
