research. However, their syntheses are generally rather tedious, requiring several steps that involve a Wagner–Meerwein‐type rearrangement under harsh conditions. Herein, we present the first copper(I)‐catalyzed oxidative CH bond functionalization and ring expansion with TMSCHN2 to yield these important derivatives in a facile and straightforward way.
三环二苯并x庚因和二苯并ze庚因是制药工业和学术研究的重要治疗剂。但是,它们的合成通常很繁琐,需要几个步骤,包括在恶劣条件下进行Wagner-Meerwein型重排。在此,我们呈现第一铜(I) -催化氧化Ç H键官能化和扩环与TMSCHN 2以容易和简单的方法,以产生这些重要的衍生物。
