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.

A novel 1,3-cycloaddition of intermediaries derived from N-(benzylidene)trimethylsilylmethylamine and acyl chlorides to conjugated olefins and acetylenes gave pyrrolidine and 2,5-dihydropyrrole derivatives, respectively.
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.

Metalation of benzophenone imines for elaboration of the alpha-amino silane component of silanediol-based protease inhibitors allows for rapid diversification of targets. Coupling this chemistry with recently developed asymmetric hydrosilylation chemistry for preparing beta-silyl acids results in a streamlined process for drug design. (C) 2013 Elsevier Ltd.
