New acridinones and enaminone esters were synthesized by microwave‐assisted tandem‐MichaelMichael addition and cyclization from cyclohexane‐1,3‐diones. The reaction mechanism for both open and closed structures, and the presence of intramolecular twelve‐membered rings derived from NH and OH H‐bonds of enaminone esters are discussed.
