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 ( Schemes 1 and 3 ).
