process has been developed for the synthesis of functionalized N‐arylsulfonylaziridines bearing an alkoxycarbonyl, acyl, cyano, and carboxamide group at C2. The two‐step sequence involves addition of N,N‐dichloroarylsulfonamide to the appropriate olefin in the presence of Cu(acac)2, treatment of the resultant chlorosulfonamide with Na2SO3, followed by cyclization with NaOH to give the appropriate aziridine
摘要 已经开发了一种方便和通用的氮丙啶化方法,用于合成在 C2 上带有烷氧基羰基、酰基、氰基和甲酰胺基团的功能化 N-芳基磺酰基氮丙啶。两步序列包括在 Cu(acac)2 存在下将 N,N-二氯芳基磺酰胺加成到合适的烯烃中,用 Na2SO3 处理所得氯磺酰胺,然后用 NaOH 环化,以良好的收率得到合适的氮丙啶。发现该反应是一种反立体选择性。
