Synthesis of 4-arylideneisochroman-1,3-dione under microwave irradiation

Homophthalic acid (1) and arylcarboxyaldehydes were condensed to form 4-arylideneisochroman-1,3-dione (3) in acetic anhydride in the presence of ammonium acetate under focused microwave irradiation. The stereochemistry of the products was determined by NMR and by X-ray diffraction of one isomer.
