on the reaction conditions and the choice of the aryne precursor, the aziridinium intermediate can be trapped through two distinct mechanistic pathways. The first one proceeds through a formal [5+2] cycloaddition to furnish valuable multi-substituted benzazepines. In the second pathway, the aziridinium is intercepted by a fluoride ion to afford allylic fluorides in good yields. Both reactions proceed
我们报告乙烯基氮丙啶和芳烃之间的环加成反应。根据反应条件和芳烃前体的选择,叠氮基中间体可以通过两种不同的机理途径被捕获。第一个过程通过正式的[5 + 2]环加成反应进行,以提供有价值的多取代苯并ze庚因。在第二种途径中,叠氮鎓被氟离子拦截,以高收率得到烯丙基氟化物。两种反应均立体定向进行,并提供对映纯的苯并ze庚因和烯丙基氟化物。
