We developed herein a palladium‐catalyzed annulation of aryltriazoles and arylisoxazoles with internal alkynes via C−H bond activation process. 4,5‐disubstituted‐3H‐naphtho[1,2‐d][1,2,3]triazoles and 4,5‐disubstituted‐naphtho[2,1‐d]isoxazoles could be afforded in good yields, respectively. The starting materials are readily available and the scope and applications of this transformation were explored
我们在本文中开发了通过CH键活化过程与内部炔烃进行钯催化的芳基三唑和芳基异恶唑的环化反应。可以分别获得4,5-二取代-3 H-萘[1,2- d ] [1,2,3]三唑和4,5-二取代-萘[2,1- d ]异恶唑。起始材料容易获得,并探讨了这种转化的范围和应用。该反应为萘稠合的杂环提供了一种实用的方法。
