A new method for the asymmetric synthesis of 2-substituted pyrrolidines in three steps from commercially available starting materials is described. Addition of the Grignard reagent prepared from 2-(2-bromoethyl)-1,3-dioxane to N-tert-butanesulfinyl aldimines proceeds in high yields and with good diastereoselectivities. The
