  • Title: Rhodium-catalyzed enantioselective cyclopropanation of olefins with N-sulfonyl 1,2,3-triazoles.
    Author: Chuprakov S, Kwok SW, Zhang L, Lercher L, Fokin VV.
    Journal: J Am Chem Soc; 2009 Dec 23; 131(50):18034-5. PubMed ID: 19928917.
    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.
