Synthetic Route of 611-09-6, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 611-09-6 as follows.
General procedure: A mixture of isatin derivatves (1 mmole), malononitrile (1 mmole),1,3-dicarbonyl compounds (1 mmole), and Fe3+-mont. (0.05 g) in CH3CN(5 mL) was heated using an Elmasonic S 40 H ultrasonic cleaning unit at 50 C under silent condition. The progress of the reaction was monitored by TLC (EtOAc/hexane 3:7). After completion of the reaction, the catalyst was removed by filtration. Water was added to the residue. The solid which was obtained was filtered off and dried to provide pure products of the spirooxindole derivatives (4a-j) (Table 3).
According to the analysis of related databases, 611-09-6, the application of this compound in the production field has become more and more popular.
