Allylic amination reactions of alkenes, with an NBP (N-bromophthalimide) or NBS (N-bromosuccinimide)/DBU combination, were developed, in which both internal and external nitrogen nucleophiles can be installed directly. Dual activation of NBS or NBP by DBU leads to more electrophilic bromine and more nucleophilic nitrogen atoms simultaneously. This protocol may provide a novel and complementary access
烯烃的烯丙基胺化反应中,与NBP(Ñ -bromophthalimide)或NBS(ñ溴代琥珀酰亚胺)/ DBU组合,被开发,其中内部和外部氮亲核试剂可以直接安装。DBU对NBS或NBP的双重激活会同时产生更多的亲电子溴和更多的亲核氮原子。该方案可以在温和条件下提供新颖和互补的烯丙基胺化途径。
