A versatile, traceless C–H activation-based approach for the synthesis of diversified heterocycles is reported. Rh(III)-catalyzed, N-amino-directed C–H alkenylation generates either olefination products or indoles (in situ annulation) in an atom- and step-economic manner at room temperature. The remarkable reactivity endowed by this directing group enables scale-up of the reaction to a 10 g scale at
据报道,一种通用的,无痕量的基于C H活化的方法可合成各种杂环。在室温下,Rh(III)催化的,N-氨基定向的C–H烯基化反应会以原子经济和分步经济的方式生成烯化产物或吲哚(原位环化)。该引导基团赋予的显着反应性使得能够在非常低的催化剂负载量(0.01 mol%/ 0.1 mol%)下将反应规模扩大至10 g规模。烯化产物的异位环化提供进入一系列杂环的入口。
