functionalization, directing‐group strategy was developed for the improvement of chemical reactivity and selectivity. Recently, to avoid the inherent limitations of traditional mono‐role directing groups, a dual‐role oxidizing‐directing‐group strategy was developed, in which the directing group acts both as directing group and oxidant. Herein, we report a multirole directing group, which possesses multiple
在过渡金属催化的CH功能化的背景下,开发了导向基团策略以提高化学反应性和选择性。最近,为了避免传统的单角色导向基团的固有局限性,开发了一种双角色氧化导向基团策略,其中导向基团既充当导向基团又充当氧化剂。在本文中,我们报道了一个多角色导向基团,该基团具有多个反应位点,表现出独特的反应性和选择性,并通过铑催化的CH活化/炔烃环化反应从一种起始原料生成四种不同类型的产物。通过调节溶剂和氧化剂,可以很好地控制出色的产品多样性以及区域和氧化还原选择性。
