Nitrogenation by direct functionalization of CH bonds represents an important strategy for constructing CN bonds. Rhodium(III)‐catalyzed direct amidation of unactivated C(sp3)H bonds is rare, especially under mild reaction conditions. Herein, a broad scope of C(sp3)H bonds are amidated under rhodium catalysis in high efficiency using 3‐substituted 1,4,2‐dioxazol‐5‐ones as the amide source. The
通过CH键的直接官能化进行的硝化是构建CN键的重要策略。铑(III)催化的未活化C(sp 3)H键直接酰胺化的现象很少,尤其是在温和的反应条件下。在此,使用3-取代的1,4,2-二恶唑-5-酮类作为酰胺源,在铑催化下高效地酰胺化了大范围的C(sp 3)H键。该协议扩大了铑(III)催化的C(sp 3)H活化化学的范围,适用于天然产物的后期功能化。
