with dimethyloxosulfonium methylide (A) and dimethylsulfonium methylide (B) yields a mixture of N-sulfinylaziridines, epimers at C-2, which are easily separated. The stereochemical outcome of this aziridination was shown to be dependent on the nature of the methylene transfer reagent. The elimination of the sulfinyl group occurs under mild conditions, leading to optically pure phenyl aziridines.
光学纯的N-亚磺酰基苯基亚胺与二甲基氧os亚甲基(A)和二甲基dimethyl亚甲基(B)的反应产生N-亚磺酰基氮丙啶的混合物,C-2的差向异构体,易于分离。该叠氮化的立体化学结果显示取决于亚甲基转移试剂的性质。亚磺酰基的消除在温和的条件下发生,从而产生光学纯的苯基氮丙啶。
