A new effective approach to synthesize a series of 7‐aryl‐6 H ,7 H ‐[1]benzopyrano[4,3‐ b ][1,3]dioxolo[4,5‐ g ][1]benzopyran‐6‐ones was reported using Fe 3 O 4 @SiO 2 @Kit‐6 as heterogeneous catalyst at room temperature under ultrasonic irradiation in aqueous media. This procedure is of great value due to its short reaction time, high yields, simple processing, and the use of easily available and magnetically recyclable heterogeneous catalyst.
