A Rh II ‐catalyzed, formal [4+1]‐cycloaddition between diazooxindoles as electrophilic C 1 synthons and 1,3‐heterodienes for the construction of spirooxindole pyrrolones is described. Employing vinyl isocyanates as 1,4‐dipoles, the cycloannulation occurs under relatively mild conditions and provides the corresponding pyrrolones in good to excellent yields.
