The syntheses of 4 H ‐benzopyran derivatives were investigated using dialdehyde as a key starting material. The reaction proceeds under microwave irradiation in good yield (87%‐95%) with short reaction time (5‐8 min), therefore providing a rapid and efficient method of synthesizing a variety of compounds containing two 4 H ‐benzopyran units.
