Alkylative ring-opening reactions of stable 2-substituted N-methylaziridinium ions proceeded with various alkyl- or arylmagnesium bromides in the presence of CuI to yield synthetically valuable and optically pure alkylated acyclic amines in a completely regio- and stereoselective manner. This was applied to a formal synthesis of the cytotoxic natural product tyroscherin.
稳定的2-取代的N-甲基叠氮鎓离子的烷基化开环反应在CuI的存在下与各种烷基或芳基溴化镁进行反应,以完全区域选择性和立体选择性的方式生成合成上有价值的和光学纯的烷基化无环胺。将其用于细胞毒性天然产物酪氨酸的正式合成。
