Benzotriazolylmethylaminosilanes, readily accessible from the reaction of benzotriazole, an aldehyde and an (aminomethyl)silane in water at 20°C, are azomethine ylide equivalents which undergo stereospecific cycloadditions with dipolarophiles to give substituted pyrrolidines or 2,5-dihydropyrroles in good yields.
