A redox‐neutral cobalt(III)‐catalyzed synthetic approach for the direct synthesis of unprotected indoles showcasing an N−N bond cleavage is reported. The herein newly introduced Boc‐protected hydrazines establish a beneficial addition to the limited portfolio of oxidizing directing groups for cobalt(III) catalysis. Moreover, the developed catalytic methodology tolerates a good variety of functional
据报道,氧化还原-中性钴(III)催化的合成方法可直接合成未保护的吲哚,显示出N-N键断裂。本文中新引入的Boc保护的肼为钴(III)催化的氧化导向基团的有限组合建立了有益的补充。此外,已开发的催化方法可耐受多种官能团。
