据报道,有一种新的策略可以通过吡啶甲酰胺辅助的钯催化的C–H键活化反应从脂肪族胺中构建复杂的多环含氮杂环。该反应显示出广泛的底物范围,可用于合成各种氮杂双环支架,包括氮杂环丁烷和托烷类生物碱。该方法在天然存在的(-)-顺式-二甲基乙胺中的应用,这是前所未有的碳-碳键活化,其中涉及的电子对引发了环钯片段的分子内“ S N 2样”置换。第三中心,描述。

Elaborating amines via C-H functionalization has been an important area of research over the past decade but has generally relied on an added directing group or sterically hindered amine approach. Since free-amine-directed C(sp3)-H activation is still primarily limited to cyclization reactions and to improve the sustainability and reaction scope of amine-based C-H activation, we present a strategy
