Nonstabilized azomethine ylides generated from the various β-amino alcohols N-oxides 13, 17, 23 and 24 undergo [3+2] cycloaddition reactions with unactivated alkenes to afford the corresponding pyrrolidines 14a-g, 18a-g, 25 and 27 in moderate to good yields. These compounds are precursors of NH pyrrolidines substituted in position 2, 3 or 4.
