General procedure: In a 15 mL quartz tube equipped with a magnetic stirrer bar, isatin (1 mmol), 1,3-dicarbonyl compound (1 mmol), malononitrile (1 mmol), and Na2 eosin Y (0.02 mmol) were added successively in ethyl lactate/water (3:1, 2 mL). The reaction tube was exposed to green LED (520e525 nm, 10 W) irradiation at a distance of approximately 3 mm from bottom of the tube (SI, Fig. S1) at room temperature in air with stirring for an appropriate time. The reaction progress was monitored by TLC. Upon completion, water was added to the mixture and the solid precipitate was filtered and washed with ethanol to obtain the desired pure product.

According to the analysis of related databases, 774-47-0, the application of this compound in the production field has become more and more popular.
