A series of 3-thienyl-6,7-methylenedioxy-1(2H,4H)-acridone derivatives are synthesized through the microwave irradiation on 5-thienyl-1,3-cyclohexanedione and the o-aminopiperonal under the solventfree condition.

Seven acridone derivatives were prepared from substituted phenyl amines and o_chlorophylgormic acid.
