α‐Ketodicarboxylic Acid Chloride Imide Chlorides in the Synthesis of Heterocycles, II: New Condensed and Spiro Rings The 5‐imino‐2,4‐pyrrolidinediones 3 and the 3‐imino‐2‐aza‐, 3‐imino‐2,8‐diaza‐, and 3‐imino‐2,5,8‐triaza‐1,4(2 H ,3 H )‐naphthalenediones 13 readily afford new condensed heterocyclic systems and heterocyclic spiro compounds via cyclocondensation, [4 + 2] cycloaddition, or 1,3‐dipolar cycloaddition.
