Rhodium-Catalyzed Enantioselective Cyclopropanation of Olefins with<i>N</i>-Sulfonyl 1,2,3-Triazoles

Abstract

N-Sulfonyl 1,2,3-triazoles readily form rhodium(II) azavinyl carbenes, which react with olefins to produce cyclopropanes with excellent diastereo- and enantioselectivity and in high yield.
