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, category: indolines-derivatives
General procedure: For compound 3, arenesulfenyl chloride (5 mmol) was added dropwise to a solution of isatin or isatin derivatives (5 mmol) and triethylamine (5 mmol) in N,N-dimethylformamide (DMF, 5 mL) at room temperature. Stirring was continued for an additional 30 min and then the mixture was poured into ice water (20 mL). The yellow precipitates were collected by filtration and recrystallized from ethanol to give pure 3a-3m.
