The transformation is initiated by electrophilic activation of the enone, which triggers two consecutive intramolecular cyclizations followed by a Ritter-type reaction. This process builds two new C–C bonds, one C–N bond, and one CO bond, affording structurally intricate tetracyclic frameworks with high efficiency. In contrast to previously reported related cyclizations, this strategy uniquely exploits both electrophilic sites of the enone and incorporates external nucleophiles beyond water, thereby substantially expanding the synthetic scope of enynone-based cationic cascade processes. The protocol exhibits broad applicability to enynone substrates and accommodates a diverse array of nitriles, underscoring its synthetic versatility. Mechanistic studies, supported by DFT calculations and experimental evidence, elucidate the origins of reactivity and selectivity.
