    • note
    • Enolate formation and subsequent elimination results in the formation of N-tosylsulfonamide, which then underwent conjugate addition to the vinyl sulfonium salt. Following a 1,3-proton shift and subsequent ring closure, the tosyl aziridine was obtained in 45 % yield. (Chemical Equation Presented)

    • note
    • Attempts to improve the diastereoselectivity through the reaction of aminal 14 with the chiral vinyl sulfonium salt 6 did not result in the formation of the desired aziridine 15. Enolization α to the imine 14 and subsequent conjugate addition of the enolate to the chiral vinyl sulfonium salt 6 gave an ylide, which underwent 1,3-proton shift and ring closure to form the α-cyclopropylimine 18.
