A C-N bond forming dearomatization protocol with broad scope is outlined. Specifically, bifunctional amino reagents are used for sequential nucleophilic and electrophilic C-N bond formations, with the latter effecting the key dearomatization step. Using this approach, γ-arylated alcohols are converted to a wide range of differentially protected spirocyclic pyrrolidines in just two or three steps.
概述了具有广泛范围的 CN 键形成脱芳构化方案。具体来说,双功能氨基试剂用于顺序亲核和亲电CN键形成,后者影响关键的脱芳构化步骤。使用这种方法,只需两到三个步骤即可将 γ-芳基化醇转化为各种差异保护的螺环吡咯烷。
