The selective O−H over N−H insertion in the reaction of isatoic anhydrides with highly reactive Rh–azavinyl carbenes (Rh‐AVC) is illustrated on the cover. Using this strategy, biologically interesting 2‐amino‐benzoxazinones and 5‐oxadiazoles were obtained under operationally simple conditions from easily available isatoic anhydrides and oxadiazolones, respecively. Furthermore, the potential of the developed protocol was demonstrated by the novel synthesis of imidazo‐fused benzoxazinones. More information can be found in the Communication by C. M. R. Volla et al. on page 2558.
