Rhodium-Catalyzed N -Allylation of Sulfoximines Using Alkyl Alkynes

Abstract

Rhodium-catalyzed N-allylation coupling reactions of sulfoximines with alkyl alkynes have been reported. The branched allylic products were obtained with a rhodium catalyst under mild reaction conditions and provided good to excellent yields of N-allylic sulfoximines. This protocol provides efficient access to diverse N-allylic sulfoximine derivatives, showing broad functional group compatibility and substantial substrate scope.
