Abstract:An efficient route for the regio- and stereoselective ring opening of N-tosylaziridines with zinc dihalides (ZnX2, X = Cl, Br, I) is described. Depending on the solvent and Zn(II) halide, β-halo amines or imidazolines are obtained selectively in good to excellent yields.
Keywords:Aziridine  Zinc(II) halide  β-Halo amine  [3+2] Cycloaddition
