β¦ Synopsis
Phenyl aziridines undergo 1,3-dipolar cycloaddition efficiently with olefins such as cyclic enol ethers and allyltrimethylsilane in the presence of a catalytic amount of Sc(OTf) 3 at ambient temperature to afford the corresponding pyrrolidine derivatives in high yields with high regioselectivity.

A silver(I)/ThioClickFerrophos complex catalyzed the endo selective asymmetric 1,3-dipolar cycloaddition reaction of methyl N-benzylideneglycinate (the source of azomethine ylides) with a,b-unsaturated esters and maleimides to give the endo-2,4,5-and 2,3,4,5-substituted pyrrolidines in good yields w
Pyrrolidines were obtained by a new, trimethylsilyl triflatecatalyzed cycloaddition of an intermediary N-trimethylsilylated methyleneiminium ylide, a 1,3-dipole, to olefinic and acetylenic dipolarophiles. Trimethylsilyl triflate (I.) has been known as an efficient catalyst for the carbon-carbon bon
## Abstract 1,3βDipolar cycloaddition of nitrones with ethyl vinyl ether or 2,3βdihydrofuran proceeds smoothly in the presence of a catalytic amount (10 mol%) of ytterbium triflate to afford isoxazolidines and dicyclic isoxazolidine respectively with good yields and high stereoselectivity.
