A novel and efficient formation of 2‐iminobenzo‐1,3‐oxathioles from readily available precursors via a copper(I)‐catalyzed one‐pot cascade process has been developed. Various 2‐iminobenzo‐1,3‐oxathioles, which might be useful in pharmaceutical and biochemical areas, were conveniently synthesized in good to excellent yields.
