The reactivity and selectivity of 1,3‐diynes in transition‐metal‐catalyzed CH activation is exploited to quickly assemble diverse polysubstituted bisheterocycles, which are highly important but difficult to access. By using the CH activation/1,3‐diyne strategy, we overcame the challenges of selectivity (chemo‐, regio‐, and mono‐/diannulation) and constructed seven kinds of adjacent bisheterocycles
的在1,3-二炔的反应性和选择性的过渡金属催化的C ^ ħ激活被利用快速组装多样多取代bisheterocycles,这是非常重要的,但难以进入。通过使用CH激活/ 1,3-二炔策略,我们克服了选择性(化学,区域和单/二色化)的挑战,并通过形成四个具有高键的策略键构建了7种相邻的双环杂环效率和高选择性。
