Nonstabilizedazomethineylidesgeneratedfrom 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.

N-Hpyrrolidines are obtained from intermolecular 3+2cycloaddition reactions between nonactivated olefins and ylide generated from amine N-oxide structurally designed in such a way as to allow easy dealkylation of the cycloadduct.
