## Abstract Isocyanides, dialkyl acetylenedicarboxylates (=dialkyl but‐2‐ynedioates), and anhydrides such as maleic anhydride (=furan‐2,3‐dione) or citraconic anhydride (=3‐methylfuran‐2,3‐dione) react in one pot to afford novel iminospiro‐__γ__‐lactones in fairly good yields at room temperature (_
