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 sulfinamide products are then cleanly converted into pyrrolidines in one step
描述了一种由市售起始原料分三步不对称合成2-取代吡咯烷的新方法。由2-(2-溴乙基)-1,3-二恶烷制备的格氏试剂向N-叔丁烷亚磺酰基醛亚胺中的添加以高收率和良好的非对映选择性进行。然后一步一步将亚磺酰胺产物干净地转化为吡咯烷。
