Functionalised N ‐heterocyclic pyridinium N ‐aminides have been designed and synthesised to evaluate a nitrenoid‐based annulation strategy into imidazole‐fused oxo‐substituted frameworks of importance to medicinal and agrochemical discovery programmes. Sulfenyl substituted ynamides were identified as privileged reactants affording productive gold‐catalysed annulation reactions with these and other nitrenoids. This annulation method provides selective and efficient access into geminally amino‐sulfenyl substituted nitrogen heterocycles under mild reaction conditions.
