    • note
    • The cyclopropanation of enones 25 and 26 with preformed ylides 8 and 19 gave low diastereoselectivity (2:1 and 1:1, respectively).

    • note
    • We also tested ylide 23 with cyclopentenone, but obtained no cyclopropanes. Use of amide-stabilized ylides 27 and 28 did produce cyclopropanes, but again with 1:1 diastereoselectivity.
