A copper-catalyzed 1,3-aminoalkynylation or 1,3-aminobromination of arylcyclopropane with N-fluorobenzenesulfonimide (NFSI) and trimethoxy[(trimethylsilyl)ethynyl]silane or LiBr have been successfully developed. Through this strategy, a wide range of γ-alkylnyl-/γ-bromino-γ-branched amine derivatives were efficiently synthesized in good yields under mild conditions.
已成功开发出铜催化的芳基环丙烷与 N-氟苯磺酰亚胺 (NFSI) 和三甲氧基[(三甲基硅基)乙炔基]硅烷或溴化锂的 1,3-氨基炔基化或 1,3-氨基溴化反应。通过该策略,在温和的条件下以良好的产率有效合成了多种γ-烷基-/γ-溴代-γ-支化胺衍生物。
