Intramolecular copper-catalyzed aziridination of sulfamates occurs in very good yields of up to 86% and in up to 84% ee in the presence of (4S,4′S)-2,2′-(propane-2,2-diyl)bis(4-tert-butyl-4,5-dihydro-1,3-oxazole). The resulting aziridines undergo smooth ring opening with different types of nucleophiles in an SN2-type process.
内部铜催化的磺酰胺环化反应在(4S,4′S)-2,2'-(丙烯-2,2-二基)双(4-叔丁基-4,5-二氢-1,3-噁唑)的存在下,产率可达86%, 恰好有高达84%的对映体过剩。所得到的氮杂环在SN2型过程中能够与不同类型的亲核试剂顺利发生开环反应。
