reactivity patterns were accessed by ynamide insertion into a C(sp3)H bond. A substantial increase in molecular complexity occurred through the cascade polycyclization of N‐allylynamides to form fused nitrogen‐heterocycle scaffolds. Exquisite selectivity was observed despite several competing pathways in an efficient gold‐catalyzed synthesis of densely functionalized C(sp3)‐rich polycycles and a copper‐catalyzed
