Adding a certain compound to certain chemical reactions, such as: 7477-63-6, name is 7-Chloroisatin, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7477-63-6, Computed Properties of C8H4ClNO2
General procedure: To mixture of isatins (1 mmol), malononitrile (1 mmol), and dimedone or 4-hydroxycoumarin or barbituric acids (1 mmol) in ethanol (4 mL), 5mg of Fe3O4APTPOSS MNPs added as the catalyst, and the mixture was stirred for an appropriate time at room temperature (Table 2). The reaction was monitored by TLC. After completion of the reaction, precipitate was filtered and dried in a drying oven to furnish 2-aminopyrano-3-carbonitriles.
