An N-(trimethylsilylmethyl)imine generates the azomethineylide1,3-dipole of nonstabilized type, when treated with water, which cycloadds to olefinic dipolarophiles in a stereospecific and regioselective manner.

Pyrrolidines were obtained by a new, trimethylsilyl triflate-catalyzed cycloaddition of an intermediary N-trimethylsilylated methyleneiminium ylide, a 1,3-dipole, to olefinic and acetylenicdipolarophiles.
